7-8 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).

7-9 HEIGHT ADJUSTMENT 

INSTRUCTIONS

CAUTION:

 Do not at any time make any 

adjustment to lawn mower 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 8 height positions.

The height (the blade to the ground) can be adjusted from 
25 mm to 70 mm (8 height positions). 

(Fig. 34)

The lowest adjustment: 25 mm (position 1), the highest 
adjustment: 70 mm (position 8).
1. Stop mower and disconnect spark plug cable before 

changing mower cutting height.

2. The central height adjustment lever offers you 8 

different height positions. 

(Fig. 34)

To change the height of cut, squeeze adjustment lever 
toward the wheel, moving up or down to selected height. 

8. MAINTENANCE 

INSTRUCTIONS

SPARK PLUG

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

BRAKE PADS

Check and/or replace the engine brake pads in service 
agent regularly, only original parts can be used as 
replacement.

9. 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.

10. 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.

10-1 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.

TO CLEAN AIR FILTER

1. Remove the screw. (

Fig. 35

 for PLM4632N and 

PLM5130N)

2. Lift the tab on the filter cover. (

Fig. 36

 for PLM4630N2 

and PLM4631N2)

3. Remove the filter cover.
4. Wash filter element in soap water. 

DO NOT USE 

GASOLINE!

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

squeeze tightly to remove any excess oil.

7. Reinstall filter.
8. Close the filter cover.

NOTE: Replace filter if frayed, torn, damaged or 
unable to be cleaned.

10-2 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. 37)

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. Refer to 

Fig. 37

. 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.
