6. MOWING TIPS
NOTE: Always inspect area where mower 
is to be used and remove all stones, 
sticks, wire, metal and other debris 
which might be thrown by the rotating 
blade.
1)  Mow across the face of slopes, never 
up-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 collection 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”. 
Remove the grass collection 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”. 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. A DULL BLADE DOES NOT 
CUT GRASS CLEANLY OR MULCH PROPERLY.
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.
