WARNING
:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
DANGER:
Before performing any maintenance, make sure the
battery is removed from the battery compartment and the
switch key is removed. Failure to heed this warning could
result in serious personal injury.
WARNING:
Do not at any time let brake fluids, gasoline,
petroleum-based products, penetrating oils, etc., come
in contact with plastic parts. Chemicals can damage,
weaken, or destroy plastic which may result in serious
personal injury.
WARNING:
Always protect hands by wearing heavy gloves and/or
wrapping the cutting edges of the blade with rags and
other material when performing blade maintenance.
Failure to heed this warning could result in serious
personal injury.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types
of commercial solvents and may be damaged by their
use. Use clean cloths to remove dirt, dust, oil, grease,
etc.
WARNING
:
Always wear safety goggles or safety glasses with side
shields during power tool operation or when blowing
dust. If environment is dusty, also wear a dust mask.
ADJUSTING THE CUTTING BLADE
See Figure 13
NOTES:
The blades have been preadjusted before leaving the
factory.
Do not adjust unless absolutely needed.
Misalignment can occur resulting in blades that are too
lose or too tight. If this happens, you will notice a rough,
uneven cut or a mower that is hard to push.
Make adjustment to the position of the cutter bar by using
a hex wrench to turn the eight adjusting bolts located on
the bottom of the cutter bar.
Adjusting the bolts is a very sensitive procedure. 1/16th of
a turn is considered a major adjustment.
Loosening the blades
The cutting bar blade is moved further from the cutting
reel.
Stop the motor and remove the switch key. Allow the
blade to come to a complete stop. Remove battery
from the battery compartment.
Use hex wrench to turn the adjusting bolts
counterclockwise.
Tightening the blades
The cutting bar is moved closer to the cutting reel.
Stop the motor and remove the switch key. Allow the
blade to come to a complete stop. Remove battery
from the battery compartment.
Use hex wrench to turn the adjusting bolts clockwise.
Periodically check all nuts and bolts for proper
tightness to ensure safe operation of the mower.
Remove any buildup of grass and leaves on or around
the motor cover. Wipe the mower clean with a dry cloth
occasionally.
Do not use water.
LUBRICATION
All of the bearings in this product are lubricated with a
sufficient amount of high grade lubricant for the life of
the unit under normal operating conditions. Therefore,
no further bearing lubrication is required.
At the beginning and end of each mowing season:
Lubricate the springs on the rear discharge flap
with light oil.
Lubricate the height adjustment knob and related
hardware with light oil.
