TILLERLUBRICATION | CHECKFOR OIL LEAKS | TRANSMISSIONGEAROIL SERVICE |
Proper lubrication of the tiller is an essential part of maintenance. After every 10 operating hours, oil or grease the lubrication points shown in Figures
Usea good quality lubricating oil (#30 weight engineoil is suitable) anda quality generalpurpose grease (with a metal lubricant, if available).

Before each use,check your tiller for
signs of an oil leak- usually a dirty, oily accumulation either on the unit or on the
floor where it has been parked.
A little seepagearound a cover or oil seal is usually not a causefor alarm. However, if the oil drips overnight then immediate attention is neededas ignoring a leak can result in severetransmission damage.
If a cover is leaking,try tightening any loose screws. If the screws are tight, a
new gasket or oil seal may berequired. If the leak is from around a shaft and oil
seal,the oil seal probably needsto be replaced. Seeyour authorizeddealer or contact the factory for service or advice.
IMPORTANT:Neveroperate the tiller if the transmission is low on oil. Checkthe
oil level after every 30 hours of operation andwhenever there is any oil leakage.
CHECKHARDWARE
Checkfor loose or missing hardware after every 10 operating hours. Tighten or replace hardware before using the tiller. Besure to check the screws underneath the tiller hood (lift the hoodflap) that securethe transmission cover andthe depth regulator leverto the transmission.
Checkthe transmission gear oil level after every30 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 Checkthe Transmission Gear Oil Level:
1. Checkthe gearoil levelwhen the trans- |
mission is cool. Gearoil will expand in |
warm operating temperatures andthis |
expansionwill provide an incorrect oil |
level reading. |
2. With the tiller on levelground, adjust |
the DepthRegulator Lever up or down to |
the notch that makesthe tiller level.. |
3. Removethe oil fill plug (A, Fig. |
from the transmission housing and look |
into the oil fill hole. You will seethe main |
drive shaft on oneside of the hole. |
4. The gear oil level is correct if the gear |
oil is approximately half way up the side |
of the drive shaft. |
5. If the gear oil level is low, add gear oil |
as described next. If the gear oil level is |
okay, securely replacethe oil fill plug. |
IMPORTANT:Do not operatethe tiller if |
the gear oil level is low. Doing so will |
result in severedamageto the transmis- |
sion components. |
6. If adding only a few ounces of gear |
oil, useAPI rated |

7.While checking frequently to avoid
overfilling, slowly add gear oil into the oil fill hole until it reachesthe halfway point on the drive shaft.
