It may be necessary to add wheel ballast or rear weights as recommended by the tractor
manufacturer to maintain stability of the machine to prevent tipping or upset which could result in
serious injury or death. See mounting instructions for specific information.

SAFETY CONTINUED
Transport the machine load at the slowest speed possible and with the loader boom at the lowest
transport position to avoid tipping or upsetting, which may result in serious injury or death.
Be extremely careful when working on inclines or near loose fill, rocks, and holes as they can cause
tipping or upsetting which may result in serious injury or death.
Be certain to avoid overhead electrical wires when operating loader. Contact with power lines may
cause serious injury or death.
Avoid sudden stops when lowering or lifting the loader boom to prevent loss of control over the
machine and/or load, which may result in serious injury or death.

in structural failure and possible serious injury or death.
Never adjust or perform maintenance on the loader or tractor with the unit in motion, or without
power source locked out.

Whenever machine is not in operation, lower the loader boom and set the tractor brakes, disengage
drive, shut the engine off, and remove the ignition key before dismounting the tractor.
If loader is to be disengaged from tractor, be sure that loader is securely supported on a hard, level
surface and that the stand is securely engaged. Be certain all connections between tractor and
loader are free before disengaging.
