Maintenance
6.4 Controls
Stiff or sluggish response of controls must be corrected immediately.
Periodically clean and lubricate the throttle cable, the throttle and
choke controls. The frequency of this maintenance will depend on
the utilization rate and the amount of dust. After performing any
maintenance on controls, saw responsiveness must be checked
before the initiation of sawing operations.
6.5 Hydrostatic Transmission
The hydrostatic transmission should not normally require maintenance.
However, the hydraulic oil level in the reservoir and the cooling fan
blade must be checked frequently.
6.6 Drive Chain
Chain tension is adjusted by loosening the four transmission bracket
mounting bolts and moving the transmission up or down as required. All
nuts must be retightened after each adjustment. Excessive tension on the
drive chains will reduce chain life and should be avoided. Periodically wipe
the chain clean and relubricate with penetrating chain lubricant.
Breakage of the drive chain will result in the loss of braking friction through
the drive wheels. Perform daily checks of the drive chain. If any damage is
noted the chain must be replaced.
6.7 Friction Drive Wheels Adjustment
If the friction drive wheels DO NOT engage the rear wheels with
sufficient pressure, slippage of the rear wheels may occur. To correct
this situation, lengthen the engagement linkage by loosening the
two (2) linkage adjustment bolts. Lengthen the linkage bars a small
amount and retighten the bolts.
6.8 Neutral Adjustment
If, due to transmission control cable or other component
replacement, the transmission control system needs to be adjusted
to obtain NEUTRAL, the following procedure must be followed:
Stop the engine and place Drive Disengage Lever in Disengage
position.
Remove the belt guard. Loosen the engine mounting bolts, remove
the v-belts and slide the engine as far forward as possible.
Loosen cable clamp on transmission control arm.
Place Transmission Speed Control lever in neutral.
