Spark Plug; Lubrication Instructions; Engine Air Cleaner; Height Adjustment - Makita PLM4630N Instruction Manual

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.
7-7 GRASS CATCHER
There is a level indicator on the top of the grass catcher
that shows whether the catcher is empty or full (Fig. 32,
Fig. 33):
- The level indicator inflates if the catcher is not full
during the moving. (Fig. 33)
- If the catcher is full, the indicator collapses; once this
happens, stop moving immediately and empty the
catcher, make sure it is clean and ensure its meshwork
is ventilated. (Fig. 32)
IMPORTANT
If the position of indicator opening is very dirty, the
indicator will not inflate-in this case, clean the position of
indicator opening immediately.
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).
