SNOWBLOWER OPERATION
Before operating the snowblower, read and understand all Safety
Instructions and Operating Instructions.
CAUTION
!
If an implement is installed on the hitch, it must be locked in place
before beginning any operation.
WARNING
!
Engaging the Snowblower
1. Set the engine throttle at about 1/3 speed. DO NOT attempt to engage the PTO clutch at high engine
speeds. This will drastically shorten drive belt life. Use only moderate engine speed when engaging the
PTO clutch.
2. Pull the PTO clutch lever SLOWLY AND SMOOTHLY to engage the snowblower.
NOTE:
For cold weather operation, allow sufficient time for the snowblower
components (i.e. gearbox oil) to warm up before beginning to blow snow.
A safety interlock switch (seat switch) will cause the engine to stop if the PTO
clutch is engaged and the operator is not in the seat. The function of this
switch should be checked by the operator raising off the seat and engaging
the PTO clutch; the engine should stop. If the switch is not working, it
should be repaired or replaced before operating the snowblower. DO NOT
disconnect the safety switches; they are for the operator’s protection.
DANGER
!
IMPORTANT: DO NOT engage the PTO clutch when transporting the
machine. DO NOT engage the PTO clutch with the PTO shaft disconnected
(the snowblower removed from the tractor).
