!
WARNING!
Unless specifically required, DO NOT have engine running
when servicing or making adjustments to the mower. Place
control levers in the park brake position and remove ignition
switch key. Repairs or maintenance requiring engine power
should be performed by trained personnel only. To prevent
carbon monoxide poisoning, be sure proper ventilation is
available when engine must be operated in an enclosed area.
Read and observe safety warnings in front of manual.
Your Razor Z was adjusted before it left the factory and
was checked during pre-delivery set-up. However, after
start-up and continued use, a certain amount of break-in
wear will cause some adjustments to change.
Remain alert for unusual noises, they could be signaling a
problem. Visually inspect the machine for any abnormal
wear or damage. A good time to detect potential problems
is while performing scheduled maintenance service.
Correcting the problem as quickly as possible is the best
insurance.
!
WARNING!
Keep your machine clean and remove heavy deposits of trash
and clippings. They can cause engine fires and hydraulic
overheating as well as excessive belt wear.
Clear away heavy build-up of grease, oil and dirt,
especially in the area of oil, fuel and engine combustion
air; minute dust particles are abrasive to close-tolerance
engine and hydraulic assemblies.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled
personnel. Consult your Land Pride service center when
assistance is needed.

first 2 hours of initial operation, and every 50 hours
following removal for repair or replacement:
•
Wheel lug nuts

Blade spindle bolts (top and bottom)
