(down) position
10. Move the drive lever to the engaged
(down) position. The drive gears should
be in contact with the tires.
11. Move the FORWARD/REVERSE switch
to both the FORWARD and REVERSE
positions. The PowrLiner should move
forward and backward if the proper
tension exists between the tires and the
drive gears.
NOTE: If adjustment to the contact tension of the drive
gears is required, loosen the turnbuckle lock nut.
Rotate the turnbuckle in the desired direction to
move the drive gears toward or away from the
tires. Tighten the turnbuckle lock nut.
12. Check the hydraulic system for leaks.
13. Turn off the PowrLiner (refer to the PowrLiner Owner’s
Manual).

(up) position
14. Move the drive lever to the disengaged
(up) position. The drive gears should
not be in contact with the tires.
15. Check the level of the hydraulic oil in
the PowrLiner hydraulic tank. Fill the
hydraulic tank with Speeflo Coolflo™
Hydraulic Fluid (P/N 430-361) until it
reaches the proper operating level.
Normal Startup
Use this procedure to start up the PowrLiner and PowrDrive for
daily operation.
1. Check the level of the hydraulic oil in the PowrLiner
hydraulic tank. If necessary, fill the hydraulic tank with
Speeflo Coolflo™ Hydraulic Fluid (P/N 430-361) until it
reaches the proper operating level.
2. Start up the PowrLiner using the normal procedure (refer
to the PowrLiner Owner’s Manual).
3. Close the bleed valve on the PowrLiner.
NOTE: The PowrDrive system will not operate properly
with the bleed valve open or with the pressure
control knob at a minimum pressure setting.
4. Turn the pressure control knob on the PowrLiner
clockwise approximately two turns.
5. Open the hydraulic shut-off valve on the PowrLiner to
activate the hydraulic system.
6. Turn the speed control counterclockwise approximately
one turn.
Drive lever
in engaged
(down) position
7. Move the drive lever to the engaged
(down) position. The drive gears should
be in contact with the tires.
8. Move the FORWARD/REVERSE switch
to both the FORWARD and REVERSE
positions. The PowrLiner should move
forward and backward if the proper
tension exists between the tires and the
drive gears.
9. Adjust the speed control to achieve a
convenient operating speed.
NOTE: It may be necessary to increase or decrease the
PowrDrive speed for hills and inclines.
IMPORTANT: The PowrLiner will continue to move for a
short distance after releasing the FORWARD/REVERSE
switch. Plan ahead to avoid causing damage to the
PowrLiner and its surroundings.
Maintenance
Perform the following steps to keep the PowrDrive running
smoothly.
1. Check the level of the hydraulic oil in the PowrLiner
hydraulic tank daily. If necessary, fill the hydraulic tank
with Speeflo Coolflo™ Hydraulic Fluid (P/N 430-361) until
it reaches the proper operating level.
2. Check all hoses for excessive wear, abrasions, and weak
spots regularly. Replace, if necessary.
3. Check all fittings for leaks regularly. Tighten, repair, or
replace as needed.
4. Check all nuts and bolts for tightness regularly. Tighten, if
necessary.
5. Check the main spur gears located under the cover at the
center of the PowrDrive monthly. Grease the gears using
a quality wheel bearing or chassis grease.
IMPORTANT: Do not use silicone-based grease.
6. Check the air pressure in the rear tires. The tires must be
properly inflated to ensure full contact with the drive gears.
