GENERAL RECOMMENDATIONS
• The mower / motor should not be reclined more than 45° when adjusting the blade setting,
servicing the machine or loading it onto trailers or other transport. This is to prevent sump oil
entering the combustion chambers. Ideally, the mower handles should be rested on the catcher
or 20 Litre drum and the engine set at ‘top dead centre’ for service work.
• When using a ramp to load the mower for transportation, avoid exposed nuts or steel
fastenings that may damage the bottom blade or cause the rear roller to skid out of control.
Particular care needs to be exercised when loading mowers with split rear rollers as they tend to
slip unpredictably on single boards.
• When cleaning the mower, avoid using pressure hoses of air or water, as these may force grit or
water into the bearings. Hosing split rear rollers will remove essential lubricants.
• Always disengage the cylinder when not cutting grass. Even short periods, such as emptying
the catcher, can scorch the grass from the heat generated between the blades.
• Care should be taken when mowing down steep inclines with mowers fitted with split rear
rollers of the ratchet type. They tend to freewheel under these conditions.
• The cutting cylinder clutch lever should only be operated when the mower is on the grassed
area and you are ready to cut the grass.
• When turning the mower, holding back the mower handle on the inside edge of the turn
facilitates the manoeuvre, more than trying to propel the outside edge of the mower handle.
SETTING UP MOWER
To obtain a parallel cut and prevent lines occurring, setting up the mower correctly is most important
and the following procedure is recommended.
Check that front roller cam height adjusters are both in the ‘high’ cut position. Turn off the petrol
and turn the engine to Top Dead Centre. Lay back the mower on 20 Litre drum or catcher. Place a
straight edge between the back and front rollers on the chain case side.
Measure from cutting edge of the bottom blade to the straight edge and adjust the front roller to the
desired cutting height. Secure the chaincase side front roller bolts.
Align, by eye, the front roller to top of the cutting blade & secure the non-chaincase side front roller
bolts. The front roller will now be parallel to the cutting blade.
Rub white chalk on the bottom of back roller so that the back roller can be aligned by eye with the
underside of the front roller.
Adjust the back roller as required by rotating the cam adjuster to raise or lower the non-chaincase end
of the rear roller. The back roller will then be parallel to the front roller that is in turn parallel to the
cutting blade. This can be checked with the straight edge.
