NORMAL MOWING
To obtain a clean cut, push the mower in straight lines (passes) at a deliberate walking pace.
Overlap the passes to even the cut and to avoid any uncut strips. Mower works best in dry grass.
Wet grass causes an uneven cut.
MOWING USING THE GRASS CATCHER (Optional Accessory) See illustrations at
beginning of manual: steps 1-8.
The grass catcher collects the clippings as it mows.
ƒ The grass catcher attaches at the grass catcher hooks located on either side of the roller
bar. The strap hooks onto the catcher and hooks onto the lower rung of the handle.
Mow using the same procedure as for normal mowing
MOWING: GENERAL INFORMATION
THE 1/3 RULE
This is the key to enjoyable mowing and a healthy lawn.
1. The lawn should be mowed regularly, at least once a week during the growing season.
2. Be guided by observing the lawn and taking care not to remove more than 1/3 of the total
height of the turf at any mowing.
3. Following this rule will stimulate the turf’s root growth, maintain its health, and encourage its
natural ability to crowd out unwanted weeds.
If the lawn has become too high (over 9 cm or 3.5 inches in height) then it is best to set the mower
to the highest setting to mow. After mowing, reset down to the normal level and mow again within
a day or two.
Removing too much of the turf’s height, especially in the heat of summer, can cause root shock and
weaken the lawn; bringing down the height by successive mowings over two or more days can
avoid this damage and maintain the health of the turf.
If the lawn is overgrown (to higher than 10 cm – 4 inches) it may be advisable to use a brush
cutter to remove the excess turf mass before resuming mowing at normal heights.
MAINTENANCE
CLEANING
After using the mower, clean with a moist cloth. Spray the cylinder and cutting bar with silicon
spray lube.
GENERAL MAINTENANCE
Regularly check to insure that all bolts, nuts, and screws are tight and that the mower is in good
working order. Worn out and damaged parts should be replaced.
The blades, if properly cared for, will mow for years before requiring sharpening. Sharpening can
only be done by a professional using a cylinder grinder and proper techniques.
SEASONAL MAINTENANCE
Readjusting the blade clearance (Fig. D, E)
The blades are optimally adjusted from the factory. However, annually, or after using the mower
for a long period and the cut is not clean, the blades need readjusting. The procedure is as follows:
1. Turn the mower over to expose the cutting bar on the bottom of the mower.
2. Using a 10mm open end wrench, tighten the hex bolt approximately 1/4 turn at one end of the
cutting bar until the cutting bar and cylinder come into contact. Spin the blade cylinder by hand
and back off the bolt approximately 1/8 turn or until the cutting bar and cylinder are no longer
in contact.
3. Make the same adjustment at the other end of the cutting bar.
