Check the pump belts daily - if tightening is necessary, loosen engine
mounts, move the engine and re-tighten.
If the engine is equipped with reducing gear please see enclosed
Briggs & Stratton instruction manual “Oil check, oil change/intervals
and oil qualities”.
Lubricate frequently the movable parts of the operating unit with
corrosion protective oil.
Change the oil of the piston pump for the first time after 50 hours’
operation and then every 150 hours or at least once a year. Fill 20/40
HD oil until it shows in the sight glass.
Be sure there is no play in the wheel bearings - use ball bearing
grease twice a year.
Check oil level of the petrol engine each day. Please see “Oil change”
Briggs & Stratton instruction book.
Off-season storage
When the spraying season is over you should devote some extra time
to the sprayer before it is stored.
Tyres
It is important frequently to check tyre pressure. The tyres should not
run under-inflated. This only promotes instability and rapid wear. See
section on Technical Specifications.
Hoses
Check that none of the hoses are caught or have sharp bends.
A leaky hose can cause annoying delay in the middle of the spraying
job. Therefore check all the hoses and change if there is any doubt
about the durability.
Paint
Some chemicals are very rough on paints. It is therefore well advised
to remove rust, if any, and then touch up the paint.
Tank
Check that no chemical residues are left from the last spraying.
Chemical residues must not be left in the tank for a long time. It will
reduce the life of the tank. See section on Cleaning the Sprayer.
