Gear cases
• To keep your drive system working properly, the gear
cases and area around the drive should be kept clean
and free of trash build-up. Clean under the drive cover
twice a season.
• The gear cases are filled with lubricant to the proper
level at the factory. The only time the lubricant needs
attention is if service has been performed on the gear
case.
• Under normal usage the grass catcher is subject to
deterioration and wear. Check the grass catcher
frequently for wear or deterioration. Replace the bag
only with grass bags that meet the manufacturer's
recommendations and specifications.
Water washout feature
Your lawn mower is equipped with a fitting that allows
quick and easy cleaning of the underside of the housing.
Note that water, grass and other debris will drain from
beneath the mower housing during the washout process.
1 Move the machine to an area of cut grass or another
hard surface.
2 Remove grass catcher or mulch plug from the lawn
mower.
3 Close the back shield.
4 Connect a garden hose to the washout port fitting.
5 Turn on water supply and check for leaks at the fitting.
6 If no leaks are present, start engine and let engine run
until the underside of the lawn mower is clean.
CAUTION! Do not engage the drive system during the
washout process.
7 Turn off the engine.
8 Shut off water supply and remove hose from fitting.
IMPORTANT! Do not remove hose from fitting while
engine is running. Water in engine can result in
shortened engine life.
9 Start engine and let engine run for a full minute to
remove excess water from mower.

MAINTENANCE

Lubrication
Use only high quality detergent oil rated with API service
classification SG-SL. Select the oil's SAE viscosity grade
according to your expected operating temperature.
-20
F
C
-30
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
CAUTION! Although multi-viscosity oils (5W30, 10W30
etc.) improve starting in cold weather, these
multi-viscosity oils will result in increased oil
consumption when used above 32°F. Check your
engine oil level more frequently to avoid possible
engine damage from running low on oil.
• Check the engine oil level before starting the engine
and after each 5 hours of continuous use. Tighten oil
plug securely each time you check the oil level.
Oil level
Before starting for the first time
• The oil tank is empty at delivery.
Fill oil to the FULL mark on the dipstick. Refer to the
manual of the engine manufacturer for details.
IMPORTANT! Do not overfill!
Check the engine's oil level
The lawn mower should stand on flat ground when you
check the oil level. Ensure the ignition lead is disconnected
from the spark plug before you open the oil filler cap.
1 Check the oil level with the dipstick on the oil filler cap.
2 Remove the oil cap and wipe the dipstick clean.
3 Put the dipstick back in. The oil filler cap must be
completely screwed on to show the oil level correctly.
4 If the oil level is low, fill engine oil to the FULL mark on
the dipstick.
