DRAGLINE OPERATION
Dragline operation requires a hoisting and an inhaul cable. The inhaul cable is on the R.H. drum. The hoisting cable is on the L.H.
drum.
Lift the bucket by engaging the L.H. clutch lever and releasing L.H. brake and at the same time releasing R.H. brake pedal to allow
bucket to swing out under the boom point as it is being lifted. After bucket is in desired position, set both brakes and disengage L.H.
clutch.
To drop bucket for digging, release the L.H. brake. To dig with the bucket, engage the R.H. clutch and release the R.H. brake as
the bucket is being pulled toward the machine. It will not fill unless additional cable is released from L.H. drum. This is
accomplished by releasing L.H. brake.
When bucket is filled, disengage R.H. clutch while setting R.H. brake. Engage L.H. clutch and release L.H. brake to hoist bucket
from the cut to the raise bucket to the dumping position. However, too much slack will allow bucket to dump early. To dump bucket
completely, release R.H. brake pedal.
CLAMSHELL OPERATION
To raise bucket, engage both R.H. and L.H. clutch levers and simultaneously release R.H. and L.H. brake pedals.
When bucket reaches desired position, set R.H. and L.H. brake pedals while disengaging clutches at the same time.
To open and lower bucket, release R.H. brake pedal for opening. As the bucket is opening, release L.H. brake pedal for lowering.
The rate of opening and lowering of bucket is controlled by pressure applied to brake pedals.
After the bucket has been set in the ground, engage R.H. drum clutch. This will close bucket. If additional cable is not let out from
L.H. drum the bucket will raise as it closes. After bucket has closed, engage L.H. drum clutch to raise. When bucket has raised to
desired height, set both brakes and at the same time, disengage both clutches.
To open bucket release L.H. brake pedal.
BACKHOE OPERATION
Backhoe operation requires a hoisting and an inhaul cable. The inhaul cable is on the R.H. drum and the hoist cable is on the L.H.
drum.
To raise backhoe boom, engage the L.H. clutch and release L.H. foot pedal. This will raise the attachment to the desired height. To
get the bucket in the desired digging position may require inward or outward spotting of the bucket.
The outward motion is accomplished by gently releasing the L.H. brake pedal. The bucket can be stopped at the desired position by
resetting the L.H. brake.
The inward motion can be accomplished by releasing the R.H. brake pedal and engaging the R.H. clutch. This motion can be
stopped at desired position by setting R.H. brake and disengaging R.H. clutch.
To lower the bucket into the cut, release the R.H. brake cautiously until the bucket reaches the ground. Engage R.H. clutch and
release R.H. brake. This will pull the bucket toward the machine, filing it. As the bucket is being pulled toward the machine,
additional cable must be released by slipping of the R.H. brake. When the bucket is filled or the extent of the travel has been
reached, set the R.H. and disengage the R.H. clutch.
To hoist the bucket from the cut, engage L.H. clutch and release L.H. brake. When required height is reached dump the bucket by
gently releasing the R.H. brake. When bucket is empty, reset L.H. and R.H brake pedals and at the same time return L.H. clutch
lever to neutral position.
SHOVEL OPERATION
Shovel operation requires hoist drum, crowd, and retract drum. Shovel operation requires the boom to be at a fixed recommended
angle.
To get boom in fixed position pull boom hoist lever to the rear. After boom is at fixed angle, move boom hoist lever to neutral
position.
To crowd shovel into bank, pull R.H. clutch lever back while releasing R.H. brake pedal. At the same time bucket is being crowded
into the bank, bucket should be hoisted. This is accomplished by engaging L.H. clutch lever and at the same time disengaging L.H.
brake pedal.
When bucket has reached desired height, return clutch levers to neutral position and set the brake pedals. To spot the bucket for
dumping, it will probably be necessary to retract the bucket. This is accomplished by engaging R.H. clutch and disengaging R.H.
brake. When bucket is spotted, set the R.H. brake and return R.H. clutch lever to neutral position.
When retracting bucket, and the load is higher than the stick pivot point, it will only be necessary to gently release the brake. When
the bucket has been spotted, set the brake and dump the bucket by pushing button on dash panel. To close bucket, gently drop
bucket by releasing L.H. brake pedal.
JIB OPERATION
To raise load, pull L.H. drum clutch lever and at the same time release L.H. brake pedal. When load has reached desired position,
set L.H. brake pedal and return L.H. clutch lever to neutral position.
To lower the load, gently release L.H. brake pedal. When load is at desired position, reset brake pedal.
PILE DRIVER OPERATION
The pile driver attachment is suspended from the boom point by adapter leads. This is raised and lowered by normal boom hoist
operation. The L.H. drum is used for raising the pile hammer.
To raise the hammer, engage L.H. clutch and disengage L.H. brake pedal. When hammer has been raised to desired height it is
dropped. This is accomplished by returning L.H. clutch to neutral. Rate of drop is controlled by L.H. brake pedal.
The R.H. drum is used for handling piling or any other requirement in usual manner.
