Cat 988 Series Large Wheel Loader Operator Trained

 Thanks for joining us for best

practices and tips for operation of cat

wheel loaders in this bolog is intended to

provide operators of case series largely

lawyers basic proficiency for efficient

machine operation this bolog will also

provide information for operators wish

to improve their knowledge on wheel

loader controls and operating procedures

case series large rear loaders this

bolog contains only theoretical content

and demonstrates pre operating and basic

operating procedures this bolog does not

attempt to certify an operator or

replace on-site training this bolog is

designed to provide you with fundamental

understanding of machine operator safety

the location and function of the

operator controls startup and shutdown

procedures and basic operating

procedures that include bucket loading

truck loading loading carry and floor

maintenance today we will walk through

these procedures and practices on the

cat 988 k when mounting or dismounting

the machine always use the ladders

stairs and steps provided and follow the

design method by using the hand holds

review the proper procedure described in

the operation and maintenance manual

face the machine while mounting and

dismounting use three points of contact

when mounting or dismounting always use

two feet in one hand or two hands and

one foot to keep a firm balance when you

move never jump off a machine from any

Heights that's an easy way to spring or

break an ankle

you could also hit your head on the

machine which would cause even more

serious injury

with several ground-level safety

features located in the rear bumper of

the machine is a stairway light switch

transmission lockout engine starter

lockout in an emergency shutdown switch

it's very important

we walk around on the machine and

visually check for any areas that may

require service or scheduled repair pay

close attention to the condition of rims

and tires inspect the linkage pins hitch

area and underside of the machine

located on the back of the machine is

the rear vision camera which can be

cleaned while standing inside the rear

bumper handrail

also located on the back of the machine

is the cat detect

backup alarm

and vams blue light

also located in the bumper

receptacle and on this tear for final

machine an amber purge light for diesel

exhaust fluid this light will turn out

when the de F fluid has been purged back

to tank at this time the operator can

turn off the battery disconnect switch

hydraulic fluid can be checked on the

side of the machine using the sight

gauge

transmission fluid level checking the

tree

mission fluid level and adding fluid

when necessary

located at ground level the loader

provides locations for fueling and

filling the auto loop system also

located at ground level is the auto lube

fill location

if equipped optional fast-fill is also

located on the fuel tank

certain tr4 final loaders use diesel

exhaust fluid or deaf the deaf fill

location is at ground level deaf must

meet International Organization for

Standardization or ISO to 2 to 4 1 - 1

the depth and fuel tank should be filled

at the same time the burn rate of depth

is typically two and a half to three

percent of your fuel burn

located inside the engine enclosure is

the engine oil dipstick and fill the

operator can verify oil level by

removing the dipstick

you

a ladder is located

side of the platform on K series loaders

cabs are also equipped with alternate

exits refer to the operation and

maintenance manual for specific

locations on each model

the upper platform allows the operator

to access the engine coolant sight gauge

and the door located on top the engine

coolant fill

before operation always inspect and

fasten your seat belt

let's review the gauges on the dash

cluster

top left corner is engine cooling below

is hydraulic temp on the right fuel

level and if equipped diesel exhaust

fluid level and torque converter

temperature now we'll cover the

indicator lights on the display starting

at the top left hand corner working in a

clockwise pattern left hand turn signal

right hand turn signal engine emission

meter hours it also indicates if the

following features are active throttle

lock auto shift engine idle shutdown

delayed engine shutdown seatbelt is on

lockup clutch and if a regeneration has

been cancelled

the right hand cab pose contains

controls for the front wiper rear wiper

your control temperature setting

and control

light switch

beacons way

if equipped

and hazard lights

we loaders are equipped with a soft

keypad here the operator can adjust

several machine settings let's review

each button starting at the top left

auto shift has two modes and mode one

you will notice that the machine will

start out in first gear by pressing Auto

shift again you are now in Auto to

driving the machine to start out in

second gear below you can use the up and

down arrows to select your max gear that

the machine will shift into next is the

lockup clutch button this disables

second gear lockup only on the loader

following this is rim pole control when

all three lights are on you have a

hundred percent rim pole

as you push the button and turn lights

out you are reducing rim poll again when

all three lights are on you have a

hundred percent rim poll the next button

is ride control this turns your ride

control system on and off following this

are your kick outs the first is your

upper kick-out press and hold the button

until it blinks and beeps the second is

you return the big kick out this sets

the level of your bucket edge if

equipped following your return to dig

kick out is your heated mirror you can

also adjust the backlight intensity by

hitting the last button and giving the

lights moving on to the second row you

have throttle lock on or off as an

operator if you choose to set throttle

lock you have to turn this button on to

set your engine RPM for machines

equipped with an auto loop system the

next button allows you to force the auto

loop to grease while you're in the cab

so you can verify the system is working

properly the next button is your lower

kick-out this stops the linkage at the

lower position by holding down until it

beeps then you have economy mode by

hitting the eco button this actually

provides throttle on-demand for the

operator engine speed is controlled

automatically the last button on the

keypad is to help assist

pushing the question mark button you can

actually hit a button that you want to

learn about on the keypad and it will

give you a description on the bottom of

the touchscreen

the graphical information display has

two home screens default as shown here

is the quad gauge showing machine

parameters the second is a work monitor

providing real-time fuel burn and

lifetime average if equipped production

information is also displayed now let's

review the navigation buttons on the

outside of the screen the first is

display settings returning to the home

screen we have machine settings

followed by totals

and then serve

and lastly operator on the right hand

side the last shortcut button on the

left side is for payload

located at the bottom of the touchscreen

is the information banner

let's review the payload homescreen and

the information that is available to you

as the operator number one displays the

total of the material loaded into the

truck

the smaller number indicates the number

of passes in the truck

bucket weight will instantly transfer to

the truck when the scale weight is

calculated number two displays the

weight of material currently in the

bucket number three displays the

remaining weight needed to achieve the

target payload for the currently

selected truck number four is bucket

zero used a zero a bucket on startup

when prompted

or when carry-back is occurring and not

able to be removed

number five is estimated weight number

six is material ID load site ID select

number seven is truck ID select number

eight is the delay code button number

nine is - one pass and truck clear

number ten is the store button this

should be pressed at the end of a truck

to store the data to memory and update

lifetime and trip payload totals below

the keypad you have the

electro-hydraulic or eh part break

and the implement lockout switch

to the right is the machine ignition

turn the key to the far right when

shutting down the machine turn the key

to the 12 o'clock position in certain

situations the machine will continue to

idle cool down and purge diesel exhaust

fluid back to tank only in an emergency

shutdown situation should you turn the

key to the orange position or 11 o'clock

also on the dash of equipped is the tr4

regeneration switch leave this switch in

automatic if the machine is key cycled

it will return to the auto by default

only in certain situations do you want

to take the machine out of automatic

regeneration mode the right-hand armrest

or implement pod has the following

controls throttle lock resume or excel

throttle lock set and decel

if equipped the turn signals

button the tilt and lift lever

equipped with softie tents

the left hand

ress contains a steering lock now in the

unlock position the operator is able to

articulate the Machine side-to-side

you can also up shift by hitting the

upper yellow button and downshift on the

lower on the bottom side of the joystick

is the forward neutral reverse switch

FNR

large wheel loaders are equipped

three pedals on the floor the first one

on the left is the impeller clutch

torque converter pedal or IC TC

this pedal actually controls rim pull or

power that is applied to the ground

while using the loader as you push in on

the pedal it cuts rim pull and

effectively reduces tire spin while

loading the bucket the last 10% of

travel is actually brake I CTC is very

important during normal operation it

allows the operator to modulate the

machine during directional changes

enables smooth transitions during the

work cycle prevents tire spin and

balances rim pull with hydraulic power

while digging with the bucket the next

pedal in line is the service brake pedal

this allows the operator to stop the

machine at any time on the far right you

have the throttle pedal this allows the

operator to manually control engine

speed during operation

green display houses the rear vision

camera which is a standard feature on

large wheel loaders if equipped the

machine may also have cat detect that

will give the operator warning of any

objects in his or her rear path

large wheel loaders are equipped with a

standard delayed engine shut down when

the operator turns the engine off by

turning the key to the 12 o'clock

position the machine will go into

delayed engine shutdown mode the

operator should not override this

feature as shown on the display you can

see that the machine is in shutdown

delay do not override only in a safety

emergency situation should the operator

turn the key to the 11 o'clock position

and override the shutdown when the

operator turns throttle lock on

and sets the engine rpm at a higher

level

after five seconds of inactivity the

machine will kick too low idle when the

operator goes back to work on the

implement pod engine speed will resume

automatically as shown here every

machine has a corresponding operation

and maintenance manual or OMM these

manuals contain warning sections on how

the machine should or should not be used

the OMM is located in the literature

holder or seat back storage area the

operator should become thoroughly

familiar with its content before

operating the wheel loader initially

before operation mirrors should be

adjusted on the outside of the cab

maximising rearward visibility or the

operator before production loading

starts the operator should set the

loader kick-outs on the soft key pad in

the cab the linkage should be positioned

before pressing the kick-out button

shown here the operator is setting the

lower kick-out just shops the bucket

before contact is made with the floor

the upper kick-out should also be set to

provide only the required amount of dumb

clearance needed for loading the truck

excessive lifting is not efficient they

returned the big kick out should also be

set to ensure the bucket edge returns to

a level position this can be done by

placing the bucket on the ground in a

level position

always maintain a smooth work floor with

good drainage keep loose rocks off the

floor wet rocks cut tires easier develop

smooth movements cheap bucket heel

slightly raised avoid tire spin by using

the left pedal I CTC use a tight B

pattern for truck loading spot the

trucks on the driver's side spot trucks

with a loaded bucket low horn the stop

trucks when spotting and when truck is

loaded

in course material pad the truck body

place the load don't throw the load into

the truck bed place the load in the

center of the truck bed

keep hoist heights to a minimum for

efficiencies and loading and to minimize

truck wear to the truck bed avoid

excessive bucket giel plate wear use

proper technique for setting adjustable

bucket kick out when digging raise the

bucket to provide heel clearance before

crowded this allows the operator to

properly set the tires the left pedal

controls the impeller clutch and brakes

depressing the left pedal reduces torque

to the wheels when all three lights are

illuminated max rim pull on the keypad

the pedal varies rim pull from a hundred

percent to roughly twenty percent as you

turn the lights out on the keypad rim

pull is reduced from 90 to 80 to 70

percent by default these settings are

adjustable in the touchscreen when the

pedal is depressed about half way the

brake begins to apply

- throttle lock the machine always run

in economy mode

this will reduce fuel consumption by up

to 20% engine speed is controlled with

left pedals and implement pod this

feature provides the efficiency of

manual throttle in the ergonomics of

throttle lock position loader one to

one-and-a-half wheel revolutions from

face to truck enter pile straight keep

frame straight when digging avoid

digging articulated transmission and

first gear when digging this provides

balance ground hydraulic speed use a

tight B pattern spot trucks at 45

degrees work face one-and-a-half to two

buckets wide minimize truck maneuvering

when loaded and wait time clean floor

between trucks keep rear truck tires off

pile keep loose rocks off the floor

create a pocket to place the truck the

pocket should be no deeper than the

distance from the bucket teeth to front

tires

keep a straight frame when digging

articulates a truck use right front tire

as a guide when spotting truck work the

face one and a half to two buckets wide

Center the load in the truck body

payload placement is critical when

loading trucks material should be

centered on the truck front to back and

side to side this will provide the most

accurate payload reading on the truck

when payload is shifted off center

excessive weight will be on the brakes

bearings tires steering components

hydraulic hoist and canopy material will

also be more prone to haul road spillage

in bolog you can clearly see the

correct way to Center the load front to

back and side to side take notice that

the operator is placing each bucket load

in the correct order

loading the center of the truck first

followed by the far sides and last the

closest half of the truck body this

results in more efficient loading and

less pushing by the loader operator

maintain optimum bucket Heights when

carrying material and a safe speed for

machine operation keep good load

retention without spillage use ride

control if equipped to help stabilize

the machine while carrying material turn

auto shift on and select mode to so the

loader will start out in second gear

after making your directional change

also set the max year in Auto shift this

will eliminate manual shifting for the

operator and increase efficiency of the

loader disable second gear lockup when

the carry distance allows for third and

fourth gear travel adjust kick outs when

necessary avoid over hoisting when

loading at lower heights

articulated digging in corner loading

this will apply excessive load on the

frames and hitch assembly causing

cracking or bearing failure wait time

with an elevated bucket this should be

reduced for best practices in site

safety never exit the cab with an

elevated bucket to ensure operator

safety all implements should be lowered

and ground engaged before exiting the

cab truck loading V pattern position

loader one to one-and-a-half wheel

revolutions from face two trucks enter

pile straight keyframes straight when

digging avoid digging articulated

transmission in first gear when digging

this provides balance ground hydraulic

speed use a tight V pattern spot trucks

at 45 degrees work face one-and-a-half

to two buckets wide minimize truck

maneuvering when loaded and wait time

clean floor between trucks keep rear

truck tires off pile keep loose rocks

off the floor

we hope that this bolog provided you

valuable best practices and tips for

optimal operations of cat k-series large

wheel loaders thank you for taking the

time .
