DO NOT attempt any maintenance, adjustments or
service with engine running. STOP engine. STOP
blades. Set brake. Remove key. Remove spark plug
wires and secure away from spark plugs. Engine and

4.3 PARKING BRAKE ADJUSTMENT

1. The parking brake can be adjusted by removing
the rod from the lever and rotating it clock-wise to
increase brake tension. When properly adjusted,
the parking brake lever should require 18 to 22
pounds of force to set the brake. If this adjustment
does not result in proper braking action contact your
authorized SNAPPER dealer for corrective action.
See Figure 4.3.

WARNING
