Maintenance Instructions; Lubrication Instructions; Cleaning - Dolmar PM-4810 Manuel D'instructions

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

12. 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.

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. Lift the tabs (19) on top of the filter cover. (Fig. 10)
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.
7. Close the filter cover.
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:
13.3 BLADE MOUNTING TORQUE
Center Bolt 40 N•m – 50 N•m, to insure safe operation of
your unit. ALL nuts and bolts must be checked periodically
for correct tightness.
After prolonged use, especially in sandy soil conditions,
the blade will become worn and lose some of the original
shape. Cutting efficiently will be reduced and the blade
should be replaced. Replace with an approved factory
replacement blade only. Possible damage resulting from
blade unbalance condition is not the responsibility of the
manufacturer.
When you change the blade, Must use the original type
marked on the blade (DOLMAR 263003054) (for order the
blade, pls. contact your local dealer or call our company).
WARNING:
• Do not touch rotating blade.
