Maintenance - General
3 MONTHS
Grease the jack; there are two grease nipples on
the sprayer's jack. One on the winding mechanism
and one on the jack swing pivot. Both need to
be greased every three months to ensure easy
operation.
Check bolts on axle bearing caps; bearing caps must
be regularly checked and tightened if required. If
dust is able to enter the axle bearings it could cause
the bearings to fail. If the gasket on the dust cap is
damaged or not sealing properly it must be replaced.
Changing Wheels
REMOVING A WHEEL
• The sprayer must be hitched to the appropriate
towing vehicle.
• The engine of the towing vehicle must be turned
off and the park brake applied.
• Chock the wheel(s) that is/are not to be removed
with an appropriate item to prevent the sprayer
from moving.
• With a wheel nut wrench, loosen all the wheel
nuts on the wheel that you wish to remove (Do
not remove wheel nuts until the tyre is off the
ground).
• Place a jack on level, firm and stable foundation
under the sprayer axle and between the two axle
bolts near the wheel to be removed. The jack
may need to have a large piece of timber or steel
placed under it so that the jack will not sink.
• Use the jack to raise the sprayer axle such that
the wheel is off the ground.
• Place an auxiliary jack block under the sprayer so
that if the jack fails the sprayer will not fall.
• Remove all wheel nuts and remove wheel from
sprayer. Be careful that the wheel does not fall on
any person and cause bodily harm.
• Ensure that the sprayer is stable when being left
for an extended period of time.
REFITTING A WHEEL
• Make sure the sprayer is stable when supported
with the jack and the jack block in place and
hitched to the appropriate towing vehicle.
44 - Chapter 10 - Lubrication & Maintenance
• Make sure the wheel is in a satisfactory condition
to use and that the tyre is inflated to the correct
tyre pressure.
• Clean the surface between the wheel and the
hub.
• Carefully lift repaired/new wheel up so that the
holes in the rim centre go over the wheel studs
on the wheel hub.
• Carefully put the wheel nuts on and tighten them
finger tight.
• With a wheel nut wrench tighten wheel nuts
alternately and evenly to a torque rating of 320 ft/
lb.
• Remove the jack block from under the sprayer.
• Carefully lower the sprayer slowly with the jack
until the tyre touches the ground.
• Retighten the wheel nuts to the required torque
rating.
• Let the jack completely down so that all weight
is taken off the jack and remove jack (and any
supports placed under the jack) from under the
sprayer.
• Remove wheel chocks that were placed to the
front and rear of the opposite wheel (to prevent
it from moving).
• Check tyre pressure before moving sprayer.
• Retighten wheel nuts to the required torque
rating: One hour after fitting the tyre, before filling
main spray tank, after the first tank load.
