maintenance schedule and troubleshooting guide for problems.
BOMAX
Trowels are designed to give many years of trouble free operation. It is, however,
important that the simple regular maintenance listed in this section is carried out. It is
recommended that an approved
BOMAX
dealer carry out all major maintenance and
repairs. Always use genuine
BOMAX
replacement parts, the use of spurious parts may
void your warranty. Before any maintenance is carried out on the equipment, switch off
the engine and disconnect the HT lead from the spark plug. Always set the equipment on
level ground to ensure any fluid levels will be correctly read. Use recommended oils only.
EQUIPMENT CLEANING
Clean the Trowel after it has been used to prevent the collection of hardened cement.
The blades can usually be cleaned with a high pressure hose and water while the
cement/concrete is still wet. Hard cement/concrete paste is very difficult to remove.
Replace decals immediately that are worn, missing, or damaged.
CHANGING BLADES
Be sure spark plug lead is disconnected before changing the blades. Make sure the
Trowel is on a flat surface. Adjust blade pitch so that the blades are flat on the surface.
CAUTION:
Be careful when changing old blades for new. Due to the way the
blades wear, the old blades become very
sharp
like a knife blade.
As a safety precaution, wear heavy-duty
gloves
during this
operation to prevent the hands being cut.
BLADES MUST BE
REPLACED AS A SET.
Remove bolts and lock washers on each Trowel arm and remove the blades. Before
fitting new blades, clean all cement/concrete from bottom and side of Trowel. Be sure
troweling edge of the blade is behind Trowel arm. Refit bolts and lock washers on each
Trowel arm and fasten them.
DRIVE BELT
CAUTION:
Rotating Parts:
Be sure to
shut
down engine
first.
Remove the belt guard then check the belt tension by placing light finger pressure on the
top of the belt, as near central between the engine drive and gearbox pulley. The belt
should deflect by between 10mm ~ 15mm. If the belt tension requires adjustment, loosen
