Major overhaul or repair of the starting motor or
alternator should be performed by trained technicians only.
Burnishing the electric clutch
WARNING: To insure maximum performance
and life, it is necessary to burnish the clutch.
Burnishing the electric clutch (Fig. 4-4) will develop
better contact between the armature and rotor, helping to
develop higher torque capabilities without slipping. The
warranty on the new clutch will be voided if it is not
burnished properly.
Use the following procedure to burnish the clutch:
1. Check the air gap between armature and rotor. Gap
should be .012” to .024”.
2. Cycle the clutch on and off 10 times (15 seconds on
and 15 seconds off) with the engine operating at half
throttles, approximately 1500 rpm.
Access to engine and hydraulic
pumps
The hydraulic pumps are accessed by lifting the seat
platform. The seat platform is hinged at the front. To raise
it, release seat latch and tilt seat platform up and forward.
The seat platform catch (Fig. 4-5) will prevent the seat from
going all the way over. However, if more access is desired
under the seat platform, the seat platform catch can be raised
allowing the seat to pivot more. Make certain to place the
control levers in the park brake position and pivot the
arm rests upward before placing the seat platform in the
full forward position to prevent arm rest damage.
WARNING: Always wear adequate eye
protection when servicing the hydraulic system
and battery.
Hydraulic system
IMPORTANT: Never use hydraulic or automatic
transmission fluid in this system; use only motor oil as
specified. Remember, dirt is the primary enemy of any
hydraulic system.
WARNING: Hydraulic oil escaping under
pressure can penetrate skin. Hydraulic oil may
cause infection in a minor cut or opening in the
skin. If exposed to hydraulic fluid, see a doctor
at once.
Before applying pressure to hydraulic system,
make sure all connections are tight and all hoses
and lines are in good condition. To find a leak
under pressure, use a piece of cardboard or wood
— never use your hands. Relieve all pressure in
the system before disconnecting or working on
hydraulic lines. To relieve pressure, lower all
attachments and shut off engine.
