Burnishing the Electric Clutch

Refer to Figure 4-3

!WARNING!

Figure 4-3WARNING: 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 & Hydraulic Pumps

Refer to Figure 4-5

The pump units are accessed under the seat platform. Raise the seat platform by releasing the seat latch and tilting the seat platform up and forward about its hinged front. A seat platform catch will prevent the seat from going all the way over. Release the seat platform catch if more room under the seat is needed and pivot the seat further forward.

IMPORTANT: Make certain to place the control arms in the park brake position and pivot the arm rests upward before placing the seat platform in the forward position.

Hydraulic System

Refer to Figure 4-6

!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.
