Prior to each work day, perform the  

following:

Daily Maintenance

Carefully remove any accumulations of 

dirt or debris from the muffler and fuel 

tank. Check cooling air intake area at 

base of crankcase.  Remove all debris. 

Dirt build-up in these areas can lead to en-

gine overheating, fire, or premature wear.
Clean any debris or dirt from the cut-

ting attachment. 

■

■

Check for loose or missing screws or 

components. Make sure the cutter at-

tachment is securely fastened.

or grease.

Gearcase Lubrication

The gearcase should be filled with 60 cc 

(2.0 fl.oz.) of Mobil SHC634 Synthetic Gear 

Oil. A maximum of 75-80 cc can be used, 

but never to exceed 80 cc. Operation with 

excessive oil level will result in high operat-

ing temperatures. 

Do not overfill!

Replacing the gearcase oil

Turn the gearcase to the LH side and 

and allow all used gearcase oil to drain 

into a small container.
