PREPARATION
Handle cutting units carefully with
protective gloves. Reels and bed
knives are very sharp. Reels rotate freely and rotating
one reel can cause other reels to rotate.
Moving machinery can be dangerous
if not operated properly. Follow all
safe operating suggestions listed in the Safety Information
section of this manual.
Check the following items before each use of the mower.
TIRE PRESSURE - Use a tire pressure gage to check
the tire pressure. Fill tires with compressed air as
needed to obtain the pressure labelled on the sidewall of
the tire.
ENGINE OIL - Check level on dipstick. Refer to the
engine manual for instructions on adding oil and which
oil viscosity to use.
CAUTION
FUEL - Check fuel level. Add fuel as required. Refer to
the engine manual for type of fuel and other safety
requirements.
ENGINE COOLING - Keep engine cowlings clear of
clippings.
LUBRICATION - Add lubricant to pivots and other
lubrication points as required. Refer to the lubrication
chart in the Maintenance section of this manual.
REELS CLEAR OF DEBRIS - Remove any debris that
may be tangled in the cutting reels. Keep the reel shaft
and bearing clean of grass or other debris buildup.
SAFETY SWITCH OPERATION - Check operation of all
safety switches. Do not use mower if safety switches are
disconnected or not operational, as dangerous conditions
will result.
DANGER
OPERATION
The following is a description of the machine controls
and their function.

engagement. Always disengage
the drive when stopping or leaving the machine.

periodically to ensure that it is adjusted to function
properly.
