Brake Maintenance
Servicing the Brake
Before each use, check the brakes on both a level surface and
slope.
Always set the parking brake when you stop the machine
or leave it unattended. If the parking brake does not hold
securely, an adjustment is required.
Checking the Parking Brake
Service Interval: Before each use or daily
1. Park the machine on a level surface and disengage the
PTO.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Apply the parking brake. Setting the parking brake
should take a reasonable amount of force. If the
parking brake does not hold securely, an adjustment is
required; refer to
Adjusting the Parking Brake (page
37) .
Note:
When the brake is engaged, the brake handle
should be in the 1 o'clock position ( Figure 48 ).
