the first time. Overlapping the cut a little on each pass will also help to clean up any stray clippings left on the 

lawn. The mower should always be operated at full throttle to get the best cut and allow it to do the most 

effective job of mowing.   

Clean underside of deck:

 Be certain to clean the underside of the cutting deck after each use to avoid a 

build-up of grass, which may affect the grass collection. The lawnmower is ideal for collecting leaves during the 

autumn months. Make sure they are dry and are not laying too thick on the lawn. Do not wait for all the leaves 

to be off the trees before you mow. 

 

WARNING: 

If the mower blade strikes a foreign object, then stop the engine. Remove the wire from the 

spark plug, thoroughly inspect the mower for any damage and repair the damage before restarting and 

operating the mower. Extensive vibration of the mower during operation is an indication of serious damage. 

The unit should be promptly inspected and repaired.   

 

6.7 GRASS CATCHER 

There is a level indicator on the top of the grass catcher that shows whether the catcher is empty or full: 

- The level indicator inflates if the catcher is not full during mowing. (Fig. 9A) 

- If the catcher is full, the indicator collapses; once this happens stop mowing immediately and empty the 

catcher, make sure it is clean and ensure its meshwork is clear of grass clippings. (Fig. 9B) 

IMPORTANT: 

Keep the grass catcher indicator vents clear at all times, to ensure that it functions correctly.

6.8 DECK 

The underside of the mower deck should be cleaned after each use to prevent a buildup of grass clippings, 

leaves, dirt or other matter. If this debris is allowed to accumulate, it will invite rust and corrosion, and may 

prevent proper mulching. The deck may be cleaned by tilting the mower and scraping clean with a suitable tool 

(make certain the spark plug wire is disconnected).
