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, 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.
Note: When the brake is engaged, the brake handle
should be in the 1 o'clock position (Figure 46).
