TILLER LUBRICATION
Proper lubrication of the tiller is an essen- tial part of your maintenance program. After every 10 operating hours, oil or grease the lubrication points shown in Figure
Use general purpose lubricating oil (#30 weight motor oil is suitable) and a general purpose grease (grease that has a metal lubricant is preferred, if available).
•Remove wheels and clean wheel shaft (A, Figure

•Grease back, front and sides of Depth Regulator Lever (B, Figure
•Remove tines and clean tine shafts (C, Figure
•Oil threads on handlebar height adjust- ment flange screw (D, Figure
•Oil threads on handlebar attaching screws (E, Figure
CHECK HARDWARE
Check unit for loose/missing hardware after every 10 operating hours. Loose or missing hardware can lead to equipment failure, poor performance, or oil leaks.
Be sure to check the three end cap mount- ing screws located at the rear of the trans- mission (Figure
Figure
CHECK TIRE PRESSURE
Check air pressure in both tires. Deflate or inflate both tires evenly to
CHECK FOR OIL LEAKS
Before each use, check tiller for signs of oil
A little seepage around a cover or oil seal is usually not cause for alarm. However, if oil drips overnight, then immediate atten- tion is
If a cover leaks, try tightening any loose screws or bolts. If fasteners are tight, a new gasket or oil seal may be needed. If leakage occurs around a shaft and oil seal, the oil seal probably needs replacement. See an authorized dealer or contact the factory for service or advice.
IMPORTANT: Never operate tiller if trans- mission is low on oil. Check oil level after every 30 hours of operation and whenever there is any oil leakage.
TRANSMISSION GEAR OIL SERVICE
Gear Oil Specifications
For small
For full replacement: Use SAE 140 or SAE
A. To Check Transmission Gear Oil Level:
1.Check gear oil level when transmission is cool. Gear oil expands when warm and will result in an incorrect oil level reading.
2.To check gear oil level (and to add oil, if necessary), see Section 2, STEP 4: Check Gear Oil Level in Transmission. Also see B. To Drain and Refill Transmission in this section.
B. To Drain and Refill the Transmission:
The transmission gear oil does not need changing unless it has been contaminated with dirt, sand or metal particles.
1.Prop up left side of unit so that it is securely supported. Remove
