• Always release bail handle to turn mower off, remove safety
key and battery pack when leaving it unattended even for a
short period oftime.
The following suggestions will help you to
obtain optimum run time from your cordless
mower:
• Slow down in areas where the grass is especially long
orthick.
• Avoid mowing when the grass is wet from rain or dew-
soaked.
• Cut your lawn frequently, especially during high
growthperiods.
NOTE: It is recommended that your mower be recharged after
use to prolong the battery life. Frequent charging will not harm
your battery, and will ensure that the battery is fully charged
and ready for its next use. Storing battery not fully charged will
shorten batterylife.
Transmission Thermal Switch
DANGER: Rotating blades can cause serious injury.
To prevent serious injury, remove safety key and
battery pack when unattended, or when charging,
cleaning, servicing, transporting, lifting, or
storingmower.
The thermal switch protects the self drive motor from
overloading and overheating that could damage themotor.
The thermal switch will automatically shut down power
to the self drive motor (not the blade motor) in the case
ofoverheating.
The reset of the thermal switch is automatic when the
transmission’s internal temperature drops below 158° F (70° C)
and the self drive bail handle is in the released (off)position.
When the thermal switch activates:
1. Remove safety key and batterypack.
2. Clean the self drive motor housing of debris. This will keep
the transmission cool. Refer to Troubleshooting Guide
inthismanual.
3. Check that the wheels are spinningfreely.
NOTE: Harsh conditions (high outside temperature, slopes,
high grass, etc.) can overheat the transmission and activate the
thermal switch if your mowing pace is too slow. Increase the
mowing speed to improve theventilation.
4. If after performing these actions the thermal switch
continues to shut down the power to the transmission stop
using the mower and contact your localdealer.
MAINTENANCE
DANGER: To reduce the risk of serious personal
injury, turn unit off, remove safety key, and remove
battery packs before making any adjustments or
removing/installing attachments or accessories. An
accidental start-up can causeinjury.
Removing and Installing Blade (Fig. J–L)
DANGER: RISK OF INJURY. WHEN REASSEMBLING THE
BLADE SYSTEM, ENSURE EACH PART IS REINSTALLED
CORRECTLY, AS DESCRIBED BELOW. IMPROPER ASSEMBLY
OF THE BLADE OR OTHER PARTS OF THE BLADE SYSTEM
MAY CAUSE SERIOUSINJURY.
DANGER: To reduce the risk of serious personal
injury, turn unit off, remove safety key, and remove
battery pack before making any adjustments or
removing/installing attachments or accessories. An
accidental start-up can causeinjury.
1. Cut a piece of 2" x 4" wood
24
(about 2 feet long)
(610mm) to keep blade from turning when removing the
flange nut
25
.
WARNING: Use gloves and proper eye protection. Turn the
mower on its side. Be careful of sharp edges of blade.
2. Position wood and unscrew flange nut counterclockwise
with a 18mm wrench
26
as shownin Fig.J.
3. Remove square metal blade spacer
27
, square plastic
blade insulator
28
and blade
29
as shown in Fig. K. The
blade fan
30
should not be removed. Examine all pieces for
damage and replace ifnecessary.
4. Install sharpened or new (STZMW353) blade
29
on
shoulder of the blade fan as shown in Fig.K.
NOTE: When replacing sharpened or new blade on shoulderof
blade fan, make sure the “GRASS SIDE” on the blade will be
facing the ground when the mower is returned to its normal
uprightposition.
5. Install the plastic blade insulator
28
on the blade such that
the raised lips on one side engage the edges of theblade.
6. Install the blade spacer
27
so that it sits inside the raised
lips on the other side of the blade insulator. Be sure to align
the flats in the hole of the blade spacer with the flats of the
shaft, rotating the blade and blade insulator together as
necessary.
7. Position piece of wood to keep blade from turning as shown
in Fig. L. Install flange nut
25
with the flange against the
blade spacer
27
and securely tighten the blade
29
with a
wrench
26
.
Blade Sharpening
KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE. A DULL
BLADE DOES NOT CUT GRASSCLEANLY.
WARNING: Use gloves and proper eye protection while
removing, sharpening, and installing blade. Ensure that
safety key and battery pack are removed.
Sharpening the blade twice during a mowing season is usually
sufficient under normal circumstances. Sand causes the blade
to dull quickly. If your lawn has sandy soil, more frequent
sharpening may berequired. REPLACE BENT OR DAMAGED
BLADEIMMEDIATELY.
When Sharpening the Blade:
• Make sure blade remainsbalanced.
• Sharpen blade at the original cuttingangle.
