Operating Instructions
Engaging the Snowblower
1.Make sure that the snowblower is clear of snow and/or ice before engaging the snowblower.
2.Make sure that the auger and fan operate freely.
3.Check the oil level in the worm gearbox and if necessary, add SAE 90 E.P. (Extreme Pres- sure) oil. Make sure the oil level is up to the side plug. (Refer to LUBRICATION of
4.Check the three (3) shear bolts, one on each au- ger section, and one between the fan and gear- box for proper tightness, approximately 8
5.Adjust the snowblower so that it runs level.
6.Set the engine throttle at about 1/3 speed. DO
NOT attempt to engage the PTO clutch at high engine speeds. This will drastically short- en drive belt life. Use only moderate engine speed when engaging the PTO clutch.
7.Pull the PTO clutch lever SLOWLY to engage the snowblower.
NOTE: For cold weather operation, allow suffi- cient time for the snowblower components (i.e., gearbox oil) to warm up before beginning to blow snow.
DANGER
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 en- gine 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.
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).
DANGER
If the auger strikes a solid object or the machine begins to vibrate abnormally, im- mediately disengage the PTO clutch, stop the engine, and wait for all moving parts to stop. Disconnect the fuel solenoid wire [diesel engines] or the spark plug wire(s) [gasoline engines] to prevent accidental starting. Thoroughly inspect the snow- blower and repair any damage before re- starting the engine and operating the machine. Make sure auger blades are in good condition and all bolts are tight.

Recommendations For Snowblowing
IMPORTANT: Operate the engine at full speed when snowblowing, to allow the engine to produce full horsepower and to increase efficiency of the en- gine cooling system.
