enough or properly supported ramps could be
dangerous. The ramps could collapse causing
the unit to fall, which could cause injury.
• Use proper ramps that are secured to the
truck or trailer.
• Keep feet and legs out from under the unit
when loading and unloading.
• If necessary, use assistance when loading.
Be sure the fuel shut-off valve is closed.
Use a heavy duty trailer to transport the machine.
