ATTACHMENTS (CONT’D)
Installing And Removing The Attachment (Power Bob-Tach) (Cont’d)
Removing
Lower the lift arms and put the attachment flat on the
ground. Lower or close any hydraulic equipment, if
applicable.
If the attachment has electrical, water, or hydraulic
connections to the loader:
1. Stop the engine and exit the loader. (See STOPPING
THE ENGINE AND LEAVING THE LOADER on Page
106.)
AVOID INJURY OR DEATH
Before you leave the operator’s seat:
• Lower the lift arms and put the attachment flat on
the ground.
• Stop the engine.
• Engage the parking brake.
• Raise the seat bar.
• Move all controls to the NEUTRAL / LOCKED
position to make sure the lift, tilt and traction
drive functions are deactivated.
The seat bar system must deactivate these functions
when the seat bar is up. See your Bobcat dealer for
service if controls do not deactivate.
W-2463-1110
2. Disconnect attachment electrical harness and water
or hydraulic lines, if applicable, from the loader. (See
Relieve Auxiliary Hydraulic Pressure (Loader And
Attachment) on Page 90.)
3. Enter the loader and perform the PRE-STARTING
PROCEDURE. (See PRE-STARTING PROCEDURE
on Page 94.)
4. Start the engine, press the PRESS TO OPERATE

Push and hold
BOB-TACH WEDGES “UP” switch (Right
Switch Panel) [Figure 137] until levers are fully raised
(wedges fully raised).
Figure 138
Tilt the Bob-Tach forward and drive the loader backward,
away from the bucket or attachment [Figure 138].
NOTE: The Power Bob-Tach system uses
continuously pressurised hydraulic fluid 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 (BOB-TACH
WEDGES “UP”) when removing an
attachment to be sure both wedges are fully
raised.
