ATTACHMENTS AND BUCKETS (CONT’D)

Power Bob-Tach™ - Removing The Bucket Or
Attachment

WARNING

Bob-Tach wedges must extend through the holes in
attachment. Levers must be fully down and locked.
Failure to secure wedges can allow attachment to
come off and cause injury or death.

W-2102-0588

Lower the lift arms and put the attachment flat on the
ground.

If the attachment is hydraulically controlled, lower or
close the hydraulic equipment before disconnecting the
quick couplers. (See Releasing Hydraulic Pressure
(Loader and Attachment) on Page 18.)

WARNING

Before you leave the operator’s seat:

Lower the lift arms, put the attachment flat on the
ground.

Stop the engine.

Engage the parking brake.

Raise seat bar.

(Foot Pedal Controls) Move pedals until both
lock.

(Advanced Control System - ACS) Move the
hydraulic controls to the NEUTRAL POSITION to
make sure that both lift and tilt functions are
deactivated.

The seat bar system must deactivate the lift and
tilt control functions when the seat bar is up.
Service the system if hand controls do not
deactivate. 

(Selectable Joystick Control - SJC) Move the
joysticks to the NEUTRAL POSITION to make
sure that travel and hydraulic functions are
deactivated.

The seat bar system must deactivate these
functions when the seat bar is up. Service the
system if controls do not deactivate.

Figure 72

Push and hold the BOB-TACH “WEDGES UP” Switch
(Front Accessory Panel) (1) [Figure 72] until the wedges
are fully raised.

Tilt the Bob-Tach forward.

Figure 73

Move the loader backward, away from the bucket or
attachment [Figure 73].

NOTE: The Power Bob-Tach system has continuous

pressurized hydraulic oil to keep the wedges
in the engaged position and prevent
attachment disengagement. Because the
wedges can slowly lower, the operator may
need to reactivate the switch (WEDGES UP)
before installing an attachment to be sure
both wedges are fully raised before installing
the attachment.

OPERATING PROCEDURE

Operating With A Full Bucket

When operating on a public road or highway, always
follow local regulations. 
For example: Slow Moving Vehicle Sign or direction
signals may be required.

Always warm the engine and hydrostatic system before
operating the loader.

IMPORTANT

Machines warmed up with moderate engine speed
and light load have longer life.

I-2015-0284

Operate the loader with engine at full speed for maximum
horsepower. Move the steering levers only a small
amount to operate the loader slowly.

New operators must operate the loader in an open area
without bystanders. Operate the controls until the loader
can be handled at an efficient and safe rate for all
conditions of the work area.

AVOID INJURY OR DEATH

Keep the lift arms as low as possible.

Do not travel or turn with the lift arms up.

Turn on level ground.

Go up and down slopes, not across them.

Keep the heavy end of the machine uphill.

Failure to obey warnings can cause the machine to 
tip or roll over and cause injury or death.

Emptying The Bucket:

Figure 80

Keep the bucket low when moving to the area where you
want to empty the bucket.

Raise the lift arms (1) [Figure 80]. Level the bucket (2)
[Figure 80] while raising the lift arms to help prevent
material from falling off the back of the bucket.

Drive forward slowly until the bucket is over the top of the
truck box or bin.

Empty the bucket (2[Figure 80]. If all the material is
near the side of the truck or bin, use the bucket tilt to
move it to the other side.

WARNING

Never dump over an obstruction, such as a post, that
