- 16 -

Keep hands and feet away from the rotating parts. Do not start the engine when standing in front of the

discharge opening.

6.3 OPERATION PROCEDURES

During operation, tightly hold the brake handle with both hands.
Note: During operation, when the brake handle is released, the engine will stop and thus stopping the

lawnmower from operating.

WARNING: In order to avoid any unintentional start-ups of the lawn mower, it comes equipped with an

engine brake which must be pulled back before the engine can be started. When the engine control lever is
released it must return to its initial position, at which point the engine automatically switches off.

Note: Engine brake (brake handle): Use the lever to stop the engine. When you release the lever the engine
and the blade stop automatically. To mow, hold the lever in the working position. Before you start to mow,
check the start/stop lever several times to be sure that it is working properly. Ensure that the tension cable can
be smoothly operated (i.e. is not catching or kinking in any way)

6.4 TO STOP ENGINE

CAUTION: The blade continues to rotate for a few seconds after the engine is shut off.

1. Release the brake control handle to stop the engine and blade.

2. Disconnect and ground the spark plug wire as instructed in the separate engine manual to prevent

accidental starting while equipment is unattended.

6.5 FOR THE BEST RESULTS WHEN MOWING

Clear lawn of debris. Be sure that the lawn is clear of stones, sticks, wire or other foreign objects which could
be accidentally thrown out by the mower in any direction and cause serious personal injury to the operator and
others as well as damage to property and surrounding objects.

Do not cut wet grass. For effective mowing do not cut wet grass because it tends to stick to the underside of

- 17 -

the deck preventing proper mowing of the grass. Cut no more than 1/3 the length of the grass. The
recommended cut for mowing is 1/3 the length of the grass. Ground speed will need to be adjusted so the
clippings can be dispersed evenly into the lawn. For 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 the 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. If a large object has been struck during mowing this could cause terminal damage to
your machine.

- 18 -

6.6 GRASS CATCHER

If the grass catcher is full of grass, you will need to empty and clean the grass
catcher, make sure it is clean and ensure its meshwork is ventilated.

Cleaning:
Wash the grass bag with a garden hose, and allow it to completely dry before

use. Cleaning the the bag will ensure optium airflow and collection.

Replacement:
Unclip the plastic edges of the bag from the frame, remove the frame from the

bag. Insert the frame into the bag, clip the plastic edges of the bag onto the
frame.

6.7 DECK

The underside of the mower deck should be cleaned after each use to prevent a build-up of grass clippings,
leaves, dirt or other matter. If this debris is allowed to accumulate, it will invite rust and corrosion of metal parts
of the mower, 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) and never tilt towards the air filter
as this can become damaged.

6.8 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 6 height positions. (Fig.9)
The height (the blade to the ground) can be adjusted from 25 mm to 75 mm (6 height positions).

1. Stop the mower and disconnect spark plug cable before changing mower cutting height.

2. The central height adjustment lever offers you 6 different height positions.

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

7. MAINTENANCE INSTRUCTIONS

SPARK PLUG

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

ENGINE BRAKE PADS

As part of the dealer service check and replace the engine brake pads as necessary.

8. LUBRICATION INSTRUCTIONS

CAUTION: Disconnect the 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.

9. 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.

9.1 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 of normal mowing. The foam
element must be serviced regularly if the mower is used in dry dusty conditions.

To CLEAN FOAM AIR FILTER

1. Remove screw.

2. Press down the two tabs on top of the filter cover. Remove cover.

3. Wash filter element in soap water. DO NOT USE PETROL!

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.

- 20 -

NOTE: Replace filter if frayed, torn,

damaged or unable to be cleaned.

Where paper filters are fitted, excess dust
and dirt may be removed by tapping it on
a hard surface several times or blowing
compressed air onto the filter.

A clean filter is essential for the efficient
operation of the mower engine.

9.2 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 re-sharpened 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 heavier 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 crankshaft. Refer to figure 12. 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:
