INSPECT BEFORE EACH USE
-Loose fasteners: Be sure all fasteners are at proper torque. Especially guards and
blades.
-Parking brake: If brake does not keep unit from rolling, brake must be adjusted
or repaired.

recommendation). Check for damage due to sharp rocks, objects or stumps.
-Operator Presence System: The engine should not start unless the PTO switch

to tighten the dipstick securely after inspection. Refer to engine manual for additional
information.
