Maintenance
4. Maintenance
4.1 General
You have purchased a virtually free maintenance machine. Generally speaking the sweeper is service free
apart from the motor. This means there is no general maintenance work.
In order to keep the machine in good general working order and maintain the value of the machine the
operator should note the following:
Motor-oil level: Check before each machine use. ( see Engine H andbook )
Air filter: Check regularly that the air filter is in order and let a dealer clean it once a year with a pressure
cleaner. If the machine is being used in a very dusty environment the user should ask the dealer how to
check the filter regularly.
Cleaning: The machine s hould be washed off with a gentle water spray and normal car cleaning materials
can be used. Do not use High pressure washers they will damage seals on service free bearings.
Check cables for wear: T he lever operated by the cable must be freely moved by the springiness of the
inner cable. D o not grease the operating levers. If the cable length needs adjusting this is achieved by
altering the adjustment screw at the operating lever (
like bicycle brakes ).
Tyre pressure: All 3 wheels have car tyre valves. The support wheel pressure should be between 1.5 and
2.2 bar. The driving wheels 1.8 bar.
The wheels should be removed once a year and a small quantity of grease applied to the moving parts.
Handle bar height adjustment: Move the locking lever up and forward (do not hit it against the motor) adjust
the handle bar height to what is required and lock the lever back. Adjust the butterfly nut to tighten.
Winter storage: If the machine is to be stored for a long period of time contact your dealer who will make
the most suitable recommendations.
4.2 Adjusting the drive belt tension
ÿ
A Warning there is a danger of trapping your fingers
If the drive starts to loose the forward motion it is probably
necessary to re-tension the drive belt tensioner. This is not
something that will happen often.
Isolate the motor by removing the spark plug lead.
Remove the rear plate of the motor section of the
machine.
Loosen the nut on the tensioner
Using a lever press the idler pulley onto the belt.
Re-tighten the nut.
