Check V-belts for deterioration and wear after 100 hours and 
replace if necessary. The belts are not adjustable. Re place 
belts if they begin to slip from wear.

Keep transaxle free from build-up of dirt and chaff which 
can restrict cooling. 

TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause 
the battery to “leak” power.
•      Disconnect BLACK battery cable fi rst  then RED  bat-

 tery cable and remove battery from tractor.

•      Rinse the battery with plain water and dry.
•         Clean terminals and battery cable ends with wire brush 

until bright.

•      Coat terminals with grease or petroleum jelly.
•      Reinstall battery (See “REPLACING BATTERY” in the 

Service and Adjustment sec tion of this manual).

TO CHANGE ENGINE OIL (See Figs. 10 and 11) 

Determine temperature range expected before oil change.  
All oil must meet API service classifi cation SF-SJ.
•      Be sure tractor is on level surface.
•      Oil will drain more freely when warm.
•      Catch oil in a suitable container.
•      Remove oil fi ll cap/dipstick.  Be careful not to allow dirt 

to enter the engine when changing oil.

•      Remove yellow cap from end of drain valve and install 

the drain tube onto the fi tting. 

•     Unlock drain valve by pushing inward and turning 

coun ter clock wise. 

•      To open, pull out on the drain valve. 
•     After oil has drained completely, close and lock the 

drain valve by pushing inward and turning clockwise 
until the pin is in the locked position as shown. 

•      Remove the drain tube and replace the cap onto to the 

bottom fi tting of the drain valve. 

•      Refi ll engine with oil through oil fi ll dipstick tube.  Pour 

slowly.  Do not overfi ll.  For approximate capacity see 
“PRODUCT SPECIFICATIONS” section of this man-
 u al.

•     Use gauge on oil fi ll cap/dipstick for checking level.  

Be sure dipstick cap is tightened securely for accurate 
reading.  Keep oil at “FULL” line on dipstick.

Only use high quality detergent oil rated with API service 
classifi cation SF-SJ.  Select the oil’s SAE viscosity grade 
according to your expected operating temperature.

NOTE:  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.

Change the oil after every 25 hours of operation or at least 
once a year if the tractor is not used for 25 hours in one 
year.

Check the crankcase oil level before starting the engine 
and after each eight (8) hours of operation.  Tighten oil fi ll 
cap/dipstick securely each time you check the oil level.   

Your engine will not run properly using a dirty air fi lter.  
Replace pre-cleaner after every 25 hours of operation or 
every season.  Service paper cartridge every 100 hours of 
operation or every season, whichever occurs fi rst.

Service air cleaner more often under dusty conditions.
•     Pull up on air fi lter cover handle and rotate towards 

engine.

•      Remove cover.
•    Carefully remove air fi lter cartridge and pre-cleaner 

from base.

•      Clean base carefully to prevent debris from falling into 

carburetor.

NOTE: If very dirty or damaged, replace cartridge.
•      Place new pre-cleaner and cartridge fi rmly in base.
•     Align tabs on cover with slots in blower housing and 

replace cover.

•     Hook handle on cover and push down on handle to 

close. 

IMPORTANT:  Petroleum solvents, such as kerosene, are 
not to be used to clean the cartridge.  They may cause 
de te ri o ra tion of the cartridge.  Do not oil cartridge.  Do not 
use pres sur ized air to clean cartridge.

Air screen must be kept free of dirt and chaff to prevent 
engine dam age from overheating.  Clean with a wire brush 
or com pressed air to re move dirt and stubborn dried gum 
fi bers.
