8-7 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).

8-8 HEIGHT ADJUSTMENT

INSTRUCTIONS

CAUTION:

Do not at any time make any

adjustment to lawnmower without first stopping the engine
and disconnecting the spark plug wire.

CAUTION:

Before changing mowing height, stop

mower and disconnect spark plug cable. Your mower is
equipped with a central height adjustment lever offering
5 height positions.
1. Stop mower and disconnect spark plug cable before

changing mower cutting height.

2. The central height adjustment lever offers you

5 different height positions.

3. To change the height of cut, squeeze adjuster lever

toward the wheel, moving up or down to selected
height

(Fig. 22)

. All wheels will be in the same height

of cut.

9. MAINTENANCE

INSTRUCTIONS

SPARK PLUG

Use only original replacement spark plug. For best
results, replace the spark plug every 100 hours of use.
(refer to ENGINE OWNER’S MANUAL)

10. LUBRICATION INSTRUCTIONS

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.

11. 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.

11-1 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.
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.

(Fig. 23 for PM-410)

11-2 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 resharpened 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.

(Fig. 24)

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 crankshaft with the “star” away from the
engine. Refer to

Fig. 24

. 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.
