6. If adding only a few ounces of gear oil, use API rated GL-4
or GL-5 gear oil having a viscosity of SAE 140, SAE 85W-140
or SAE 80W-90. If refilling an empty transmission, use only
GL-4 gear oil having a viscosity of SAE 85W-140 or SAE 140.
7. While checking frequently to avoid overfilling, slowly add
gear oil into the oil fill hole until it reaches the halfway
point on the drive shaft.
8. Securely replace the oil fill plug.
Lubrication
After every 10 operating hours, oil or grease the lubrication
described below. Use clean lubricating oil (#30 weight motor oil
is suitable) and clean general purpose grease (grease containing
a metal lubricant is preferred, if available).
• Remove the wheels, clean the wheel shaft and apply a thin
coating of grease.
• Remove the tines and clean the tine shaft. Use a file or
sandpaper to gently remove any rust, burrs or rough spots
(especially around the holes in the shaft). Apply grease to
the ends of the shaft before installing the tines.
• Oil the handlebar hardware.
Off-Season Storage
When the tiller won't be used for an extended period, prepare it
for storage as follows:
1. Clean the tiller and engine.
2. Do routine tiller lubrication and check for loose parts and
hardware.
3. Service the engine as instructed in the separate engine
manual.
4. Engines stored between 30 and 90 days need to be treated
with a gasoline stabilizer such as STA-BIL® and engines
stored over 90 days need to be drained of fuel to prevent
deterioration and gum from forming in fuel system or on
essential carburetor parts. If the gasoline in your engine
deteriorates during storage, you may need to have the
carburetor, and other fuel system components, serviced or
replaced.
WARNING:
container outdoors, away from an open flame. Allow
engine to cool. Extinguish cigarettes, cigars, pipes,
and other sources of ignition prior to draining fuel.
5. Store the tiller in a clean, dry area.
6. Never store the tiller with fuel in the fuel tank in an
enclosed area where gas fumes could reach an open flame
or spark, or where ignition sources are present (space
heaters, hot water heaters, furnaces, etc.).
