4 - Every 10 operating hours.

5 - Every 30 operating hours.

6 - Change more frequently in dusty or dirty conditions.

7 - See Engine Owner’s Manual for service recommendations.

8 - Whichever time interval occurs first.

9 - Change after first 2 hours of break-in operation.

TILLER LUBRICATION

After every 10 operating hours, oil or grease the lubrication points shown in Figure 5-1 and 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 (A, Fig. 5-1) and apply a thin coating of grease to the wheel shaft.

Grease the back, front and sides of the depth regulator lever (B, Fig. 5-1).

Remove the tines and clean the tine shaft (C, Fig. 5-1). Use a file or sandpaper to gently remove any rust, burrs or rough spots (especially around holes in shaft). Apply grease to ends of shaft before installing tines.

Oil the threads on the handlebar height adjustment screws and the handlebar attaching screws (D, Fig. 5-1).

CHECK FOR OIL LEAKS

Before each use, check the tiller for signs of an oil leak – usually a dirty, oily accu- mulation either on the unit or on the floor.

A little seepage around a cover or an oil seal is usually not a cause for alarm. How- ever, if the oil drips overnight, then imme- diate attention is needed. Ignoring an oil leak can result in severe transmission damage!

If a cover is leaking, check for loose screws. If the screws are tight, a new gasket or oil seal may be required.

If the leak is from around a shaft and oil seal, the oil seal probably needs to be replaced. See your authorized dealer or contact the factory for service or advice.

IMPORTANT: Never operate the tiller if the transmission is low on oil. Check the oil level after every 30 hours of operation and whenever there is any oil leakage.

CHECK HARDWARE

Check for loose or missing hardware after every 10 operating hours and tighten or replace (as needed) before reusing tiller

Be sure to check the screws underneath the tiller hood that secure the transmission cover and the Depth Regulator Lever to the transmission.

CHECK TIRE PRESSURE

(Models with pneumatic tires)

Check the air pressure in both tires. The air pressure should be between 15-20 PSI (pounds per square inch).

Keep both tires equally inflated to help prevent machine from pulling to one side.

TRANSMISSION GEAR

OIL SERVICE

Check the transmission gear oil level after every 30 hours of operation or whenever you notice any oil leak. Operating the tiller when the transmission is low on oil can result in severe damage.

A. To Check the Transmission

Gear Oil Level:

1.Check the gear oil level when the trans- mission is cool. Gear oil will expand in warm operating temperatures and this expansion will provide an incorrect oil level reading.

2.With the tiller on level ground, pull the Depth Regulator Lever all the way up.

3.Remove the oil fill plug (A, Fig. 5-2) from the transmission housing and look inside the oil fill hole to locate the main drive shaft situated below the hole.
