and-down. Exercise extreme caution when 
changing direction on slopes. Do not mow 
excessively steep slopes. Always maintain 
good footing.
2.  Release switch lever to turn mower “OFF” 
when crossing any graveled area (stones 
can be thrown by the blade).
3.  Set mower at highest cutting height when 
mowing in rough ground or in tall weeds. 
Removing too much grass at one time can 
cause circuit breaker to trip, which stops 
mower. 
4. 
 If a grass bag is used during the fast 
growing season, the grass may tend to clog 
up at the discharge opening. Release switch 
lever to turn mower “OFF” and remove 
the safety key. Remove the grass bag and 
shake the grass down to the back end of 
the bag. Also clean out any grass or debris 
which may be packed around the discharge 
opening. Replace the grass collection bag.
5.  If mower should start to vibrate 
abnormally, release switch lever to turn 
mower “OFF” and remove safety key. 
Check immediately for cause. Vibration is a 
warning of trouble. Do not operate mower 
until a service check has been made. 
6. ALWAYS RELEASE SWITCH LEVER TO 
TURN MOWER “OFF” AND REMOVE 
SAFETY KEY WHEN LEAVING IT 
UNATTENDED EVEN FOR A SHORT 
PERIOD OF TIME.
MAINTENANCE
WARNING: Stop the mower and 
remove the safety key before 
removing the grass bag.
NOTE: To ensure long and reliable service, 
perform the following maintenance 
procedures regularly. Check for obvious 
defects such as a loose, dislodged or a 
damaged blade, loose fittings, and worn 
or damaged components. Check that the 
covers and guards are all undamaged and 
are correctly attached to mower. Carry out 
any necessary maintenance or repairs before 
operating mower.  If the mower should 
happen to fail despite regular maintenance, 
please call our customer helpline for advice. 
BLADE SHARPENING
KEEP BLADE SHARP FOR BEST MOWER 
PERFORMANCE.  
WEAR PROPER EYE PROTECTION WHILE 
REMOVING, SHARPENING, AND INSTALLING 
BLADE. ENSURE THAT SAFETY KEY IS 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 be required.
REPLACE BENT OR DAMAGED BLADE 
IMMEDIATELY.
WHEN SHARPENING THE BLADE:
1.   Make sure blade remains balanced.
2.  Sharpen blade at the original cutting angle.
3.  Sharpen cutting edges on both ends of 
blade, removing equal amounts of material 
from both ends.
TO SHARPEN BLADE IN A VISE  
(See Fig. K)
1.   Be sure the switch lever is released, the 
blade has stopped and the safety key 
removed  before  removing  the  blade.                                                                    
2.  Remove blade from mower. See 
instructions for removing and attaching 
blade.
3.  Secure blade K-1 in a vise K-2.
4.  Wear safety glasses and be careful not to 
cut yourself.
5.  Carefully file the cutting edges of the blade 
with a fine tooth file K-3 or sharpening 
stone.
6.  Check balance of blade. See instructions 
for blade balancing.
7.   Replace blade on mower and tighten 
securely. Refer to instructions below.
BLADE BALANCING (See Fig. L)
Check balance of blade by placing center hole 
in blade L-1 over a nail or screwdriver shank L 
-2, clamped horizontally in a vise L-3. If either
end of the blade rotates downward, file that 
end. Blade is properly balanced when neither 
end drops.
BLADE MAINTENANCE (See Fig. M1,M2)
Renew your metal blade after 50 hours
