Engine Maintenance - Murray 1695691 Operator's Manual

MAINTENANCE
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 A , Figure 23), once a year. 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. Mobilux EP1 and Shell Alvania
EP1 are suitable equivalents.
LUBRICATE AUGER SHAFT FITTINGS
1. Using a hand grease gun, lubricate the auger shaft fittings (B B , Figure
23) every ten (10) operating hours. Each time a shear pin is replaced,
the auger shaft (C C ) MUST be greased. (See "Auger Shear Pin
Replacement" section.)
2. For storage or when replacing shear pins, remove shear pins and
lubricate auger shaft fittings (B B ). Rotate augers several times on the
shaft and reinstall the shear pins.
LUBRICATE CONTROL LEVER LINKAGE
The controls should function as described in the OPERATION section.
WARNING: It is critical for the safe operation of the unit
that the controls disengage when released.
Lubricate the linkage for the traction control (A A , Figure 24), speed select
control (B B ), and auger control (C C ) every ten (10) operating hours, or as
necessary to ensure safe operation.
NOTICE: Under no circumstances should the unit be used if the
controls do not function properly.
LUBRICATE CHUTE ROTATION GEAR
Lubricate the chute rotation gear (A A , Figure 25) and shaft (B B ) with
automotive type oil every twenty-five (25) operating hours.
ADJUST THE DRAG ON THE CHUTE ROTATION
NOTE: After repeated use, the chute rotation gear may loosen,
causing the chute to move back to the center position.
Adjust the drag by tightening the nut (C C , Figure 25). Tightening the nut
will limit the chute from moving without the operator turning the chute
rotation crank.

ENGINE MAINTENANCE

Check Crankcase Oil Level - Before starting engine and after each 8
hours of continuous use. Add the recommended motor oil as required.
NOTE: Over filling the engine can affect performance. Tighten
the oil fill cap securely to prevent leakage.
Change Oil - Every 50 hours of operation or at least once a year, even if
the snow thrower is not used for fifty hours. Use a clean, high quality
detergent oil. Fill the crankcase to FULL line on dipstick (A A , Figure 26). Be
sure original container is marked: A.P.I. service "SF" or higher. Do not use
SAE10W40 oil (as it may not provide proper lubrication). See Chart for
oil recommendations.
Drain Oil – Position snow thrower so that the oil drain plug (A A , Figure
27) is lowest point on engine. When the engine is warm, remove oil drain
plug and oil fill cap and drain oil into a suitable container.
Replace oil drain plug and tighten securely. Refill crankcase with the
recommended motor oil.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W-30 may cause increased oil consumption. Check oil
level more frequently.
