the other end to the positive terminal of
the discharged battery.
DO NOT
permit
units to touch each other.
3. Attach one end of remaining cable to the
negative terminal of the booster battery
and the other end to a good ground on the
unit or engine, away from the discharged
battery.
DO NOT
lean over the battery
when making this connection.
Reverse this sequence exactly when removing the
jumper cables.
NOTICE
• Booster batteries used for starting must be
connected with proper polarity.
TYRE PRESSURE
CAUTION
•
Caution must be used when inflating a low
tyre to recommended pressure. Check
pressure with a low pressure tire gauge
before connecting an air hose to a partly
inflated tire.
CAUTION
•
Due to the low air volume requirements of
a small tyre, over inflation may be reached
in a matter of a few seconds, which could
cause the tire to explode.
COLD INFLATION PRESSURE
All Tires 9 PSI (60.3 kPa)
NOTICE
• Improper inflation will reduce tire life
considerably
CUTTING HEAD MAINTENANCE
CLEANING
The cutting heads should be washed after each days
use and dried as well as possible to prevent rust.
All cutting surfaces (reel and bedknife) should be
given a light coating of oil or other anti–rust
compound.
LUBRICATION
The lubrication fittings at each end of both the front
and rear rollers, as well as the reel bearings at each
end should be lubricated periodically (approximately
once each week). Use only enough lubricant to keep
the bearings from drying out. Too much lubricant
may drop from mower onto turf, causing damage to
the grass.

BACKLAPPING
Backlapping on a regular basis will help keep the
cutting edges sharp and extend the life of the reel.
Backlapping may be performed on one cutting head
only, two heads, or all three heads simultaneously. If
backlapping one or two cutting heads is desired,
back off slightly on the bedknife–to–reel clearance
on the head(s) not requiring backlapping. This will
eliminate contact between bedknife and reel,
avoiding the possibility of damaging the reel or
bedknife during the backlap process. Always make
bedknife adjustments with the Engine Off.
NOTICE
• Make sure the bedknife adjustment is
correct before backlapping. Refer to
Bedknife Adjustment (Page 7).
WARNING
• ALWAYS
open the restriction valve before
setting the reel control lever to
BACKLAP
position
. DO NOT
set the reel control
lever to the
BACKLAP
position before
opening the needle valve in the bypass
circuit. This will cause the reels to start
turning
IMMEDIATELY
at full speed.
•
Keep hands, feet and clothing away from
all three reels whenever the reel control
lever is placed in the backlap position.
When backlap restriction valve is
closed
or being closed
, all
three reels will rotate
in
the backlap direction.
1. Open the restriction valve on the reel
valve by turning the knob
counterclockwise as far as it will go (See
Fig. 36).
