Engine Maintenance
For engine maintenance schedules and procedures, please refer to the engine operator's
manual.
Control Lever Linkage Lubrication
Check the function of the Free Hand control (A, Figure 12). The controls should function as
described in the
Operation section.
WARNING
Amputation hazard
It is critical for safe operation of the unit that the controls disengage when released. Under
no circumstances should the unit be used if the controls do not function properly. See
Safety Systems Tests to confirm correct operation.
Lubricate the linkage for the Free Hand control, speed select control, and Easy Turn/Easy
Steer control every ten operating hours, or as necessary to ensure safe operation.
Auger Assembly Lubrication
Lubricate Auger Gear Box
The auger gear box is lubricated at the factory and should not require additional lubrication.
If for some reason the lubricant should leak out, or if the auger gear box has been serviced,
add Lubriplate GR132 Grease or equivalent. Maximum 3-1/4 ounces, (92 grams) should
be used.
Remove filler plug (A, Figure 13), once a year to check grease level. If grease is visible, do
not add. If grease is not visible, use a piece of fine wire, like a dipstick to check if there is
grease in the gear box.
Lubricate Auger Shaft Fittings
Using a grease gun, lubricate the auger shaft fittings (B, Figure 13) every 25 operating hours,
or once per season. Each time a shear bolt or pin (C) is replaced, the auger shaft MUST be
greased.
For storage or when replacing shear bolts or pins, remove the shear bolts or pins (C),
lubricate the shaft fittings (B), and rotate the augers several times to distribute the grease.
Reinstall the shear bolts or pins when complete.
Discharge Chute and Deflector Lubrication
Lubricate the chute rotation gear (Figure 14) with grease, and the deflector mechanism with
automotive type oil every twenty five operating hours.
Where an oil can is pictured, lubricate with engine oil. Where a grease gun is pictured,
lubricate with lithium grease.
Hex Shaft and Chain Lubrication
The hex shaft and drive chains must be lubricated at the interval specified in the Maintenance
Chart . Please have your authorized dealer perform this maintenance.
Traction Cable Inspection
The cables are adjusted at the factory and no adjustment should be necessary. However,
if the cables have become stretched or are sagging, adjustment will be necessary. Please
see your dealer for this adjustment.
Traction Drive Belt Adjustment
The traction drive belt is under constant spring tension and does not require any adjustment.
If the traction drive belt is slipping, see your authorized dealer.
Speed Control Rod Adjustment
If the speed control rod requires adjustment, see an authorized dealer.
Easy Turn™ Cable Adjustment
If the Easy Turn cable has stretched, the gears will not disengage when the control lever is
activated. Adjust the cable using the following procedure.
1.
Turn the engine off and remove the key.
2. Loosen the jam nut (A, Figure 15).
3. Turn the adjustment nut (B) to lengthen or shorten the cable. The cable should be
tightened until all slack is removed from the lever. However, it must not engage the
Easy Turn without depressing the control lever.
4. Tighten the jam nut (A).
Auger Cable Adjustment
WARNING
Amputation hazard
Over-tighten the auger cable may cause the auger drive to engage without depressing
the auger drive control.
Follow the adjustment procedure to ensure the cable is not over-tightened.
1. With the auger control lever released, the hook (A, Figure 16) should barely touch the
lever (B) without raising it. There can be a maximum of 1/32" (0.8 mm) clearance.
2. To adjust, loosen the nut (C) by holding the adjusting flats (D) and turning the nut.
Then, turn the adjusting flats and hold the adjustment screw (E). The adjustment screw
is a Phillips screw and the head can be held or turned by inserting a screwdriver
through the spring (F).
3. Hold the adjusting flats and tighten the nut.
4. To ensure that the auger does not engage unless the control is fully depressed, please
perform the
Safety System Tests. The auger must stop within 5 seconds of the
control being released.
Determine Which Shear Bolt/Pin System
You Have
Please refer to the Illustrated Parts List to determine if your unit requires a shear bolt or
shearbolt and spacer combination.
DANGER
Amputation hazard
The discharge chute contains a rotating impeller to throw snow. Fingers can quickly
become caught and traumatic amputation or severe laceration will result. Hand contact
with the rotating impeller inside the discharge chute is the most common cause of injury
associated with snowthrowers.
Turn the engine OFF, wait for all moving parts to stop, and remove the engine key before
performing any maintenance or repairs.
Shear Pin Replacement
Augers are secured to the auger shaft with special pins that are designed to break if an
object becomes lodged in the auger housing. Use only factory spec, or equivalent, shear
pins.
