especially heavy cutting in thick grass it may be 
necessary to use one of the slowest speeds in order to get 
a clean well mowed cut. When mowing long grass you 
may have to cut the lawn in two passes, lowering the 
blade another 1/3 of the length for the second cut and 
perhaps cutting in a different pattern than was used the 
first time. Overlapping the cut a little on each pass will 
also help to clean up any stray clippings left on the lawn. 
The mower should always be operated at full throttle to 
get the best cut and allow it to do the most effective job of 
mowing. Clean underside of deck. Be certain to clean the 
underside of the cutting deck after each use to avoid a 
build-up of grass, which would prevent proper mulching. 
Mowing leaves. The mowing of leaves can also be 
beneficial to your lawn. When mowing leaves make sure 
they are dry and are not laying too thick on the lawn. Do 
not wait for all the leaves to be off the trees before you 
mow.

WARNING: 

If you strike a foreign object, stop the 

engine. Remove wire from spark plug, thoroughly inspect 
the mower for any damage and repair the damage before 
restarting and operating the mower. Extensive vibration of 
the mower during operation is an indication of damage. 
The unit should be promptly inspected and repaired.

10-7 DECK

The underside of the mower deck should be cleaned after 
each use to prevent a buildup of grass clippings, leaves, 
dirt or other matter. If this debris is allowed to accumulate, 
it will invite rust and corrosion, and may prevent proper 
mulching. The deck may be cleaned by tilting the mower 
and scraping clean with a suitable tool (make certain the 
spark plug wire is disconnected).

11. MAINTENANCE 

INSTRUCTIONS

SPARK PLUG

Use only original replacement spark plug. For best 
results, replace the spark plug every 100 hours of use.

12. LUBRICATION INSTRUCIONS

CAUTION:

 DISCONNECT SPARK PLUG 

BEFORE SERVICING.
1. WHEELS-Lubricate the ball bearings in each wheel at 

least once a season with a light oil.

2. ENGINE-Follow engine manual for lubrication 

instructions.

3. BLADE CONTROL-Lubricate the pivot points on the 

blade control handle and the brake cable at least once 
a season with light oil. The blade control must operate 
freely in both directions.

13. CLEANING

CAUTION:

 Do not hose engine. Water can 

damage engine or contaminate the fuel system.

1. Wipe deck with dry cloth.
2. Hose under deck by tilting the mower so that the spark 

plug is up.

13-1 ENGINE AIR CLEANER

CAUTION:

 Do not allow dirt or dust to clog the air 

filter foam element. The engine air cleaner element must 
be serviced (cleaned) after 25 hours normal mowing. The 
foam element must be serviced regularly if the mower is 
used in dry dusty conditions. (Refer to ENGINE 
OWNER’S MANUAL)

To CLEAN AIR FILTER

1. Remove screw. 

(Fig. 10A, Fig. 10B)

2. Remove cover.
3. Wash filter element in soap water. 

DO NOT USE 

GASOLINE!

4. Air dry filter element.
5. Place a few drops of SAE30 oil on the foam filter and 

squeeze tightly to remove any excess oil.

6. Reinstall filter.

NOTE:

 Replace filter if frayed, torn, damaged or 

unable to be cleaned.

13-2 CUTTING BLADE

CAUTION:

 Be sure to disconnect and ground the 

spark plug wire before working on the cutting blade to 
prevent accidental engine starting. Protect hands by using 
heavy gloves or a rag to grasp the cutting blades. Tip 
mower as specified in separate engine manual. Remove 
the hex bolt and washer which hold the blade and blade 
adapter to the engine crankshaft. Remove the blade and 
adapter from the crankshaft. 

WARNING:

 Periodically inspect the blade 

adapter for cracks, especially if you strike a foreign object. 
Replace when necessary.
For best results your blade should be sharp. The blade 
may be retargeted by removing it and either grinding or 
filing the cutting edge keeping as close to the original 
bevel as possible. It is extremely important that each 
cutting edge receives an equal amount of grinding to 
prevent an unbalanced blade. Improper blade balance will 
result in excessive vibration causing eventual damage to 
the engine and mower. Be sure to carefully balance blade 
after sharpening. The blade can be tested for balance by 
balancing it on a round shaft screwdriver. Remove metal 
from the heavy side until it balances evenly.
Before reassembling the blade and the blade adapter to 
the unit, lubricate the engine crankshaft and the inner 
surface of the blade adapter with light oil. Install the blade 
adapter on the engine crankshaft. Refer to 

Fig. 11

. Place 

the blade with the part number facing away from the 
adapter. Align the washer over the blade and insert the 
hex bolt. Tighten the hex bolt to the torque listed below:
