8-5 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 the
deck preventing proper mowing of the grass clippings. 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 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.
8-6 GRASS CATCHER
Empty and clean the bag, make sure it is clean and
ensure its meshwork is ventilated. (Fig. 23)
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 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
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. 24). 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)
BRAKE PADS
Check and/or replace the engine brake pads in service
agent regularly, only original parts can be used as
replacement.
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. STOP CONTROL-Lubricate the pivot points on the
stop control handle and its cable at least once a
season with light oil. The stop 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)
