Operation
16. Vi sually ensur
e that both coupler pins are
extending out of the holes in the work tool
mounting bracket.
17. Use the following procedure to verify engagement
of the coupler pins.
a. Enter the machine.
b. Fasten the sea
t belt and lower the armrest.
c. Start the engine.
d. Disengage the parking brake.
e. Keep the work t
ool close to the ground.
f. Activate the tilt control in order to tilt the work
tool downward
.
g. Apply down pressure on the work tool.
Note: The work tool Owner’s Manual will inform you
if forward pressure should not be applied on a work
tool.
h. Move the machine backward. Ensure that there
is no movemen
t between the work tool and the
quick coupler assembly.
18. Te s t t h e w o r k
tool for leaks and for proper
operation.
Removing the Work Tool
Disengaging the coupler pins will release t he work
tool from c
ontrol of the operator.
Serious injury or death m ay result from disengag-
ing the wor
k tool wh en it is in an unstable position
or carrying a load.
Place the w
ork tool in a safe position before dis-
engaging the coupler pins.
NOTICE
Auxiliary hoses for work tools must be disconnected
before the quick coupler is disengaged.
Pulling the work tool with the auxiliary hoses could
result in damage to the host machine or the work tool.
1. Position the machine on level ground.
2. Lower the work tool to the ground.
3. Rack back the wo
rk tool until the work tool is
slightly off the ground.
4. Turn the engin
e start switch key to the OFF
position in order to stop the engine.
5. If the work too
l requires hydraulics, refer to
the section “Releasing the Hydraulic System
Pressure”.
6. Perform Step 7 through Step 12 only after you
have released the hydraulic system pressure.
7. Disconnect the auxiliary hydraulic hoses from the
machine.
Note: If protective caps are available, install
protective caps over the quick connect couplers.
8. If hoses are routed through the hose guide,
remove the hoses from the hose guide. Move the
hoses to a po
sition that is away from the work tool
mounting bracket.
Note: Conne
ct the hoses for the work tool together.
Connecting the hoses together will reduce the
probability of contaminating the hydraulic system.
Connecting
the hoses together will reduce the
buildup of pressure in the hoses. Connecting the
hoses together will ease the connection of the hoses
to the mach
ine.

line, then
disconnect the wire harness from the
connector on the machine. If protective caps are
available, install protective caps over the electrical
connecto
rs.
10. If the auxiliary electrical line is routed through the
hose guid
e, remove the line from the hose guide.
Move the auxiliary electrical line to a position that
is away from the work tool mounting bracket.
11. If the work tool is equipped with a water line, then
disconnect the water line from the connector on
the mach
ine. Move the water line to a position that
is away from the work tool mounting bracket.
12. Exit the
machine.
Note: If you are removing a material handling arm
that is n
ot equipped with an optional center step,
do not exit the machine. A second person needs to
perform step 13.
