Regular Maintenance
Lubrication
At least once a season apply grease to all
the rotation points on the SR28. Use a
grease gun to apply grease to the grease
nipples on the wheels and caster bearings
and spray white lithium grease to lubricate
the remaining points. (circled at right).
Hoses and Fittings
Do a visual check
at least once a month
of
all hoses and fittings to make sure there is
no damage or risk of perforation. Replace
any parts BEFORE they fail.
Tires
Check tire pressures frequently. Check the
tread, especially on the right hand 10” wheel
that takes most of the weight of the
machine. Replace the wheel if necessary.
Heaters
Over time the heaters may begin to lose some of their original glow so
that it takes longer to heat the asphalt. One way to prevent this is to
keep the propane tips (orifices) clear of debris. The orifice is the small
tip that injects the propane into the heater. Use the supplied tip cleaner
to clean out the orifice.
To do this, attach compressed air onto the quick coupler on the hose
leading into the heater bank. Run the tip cleaner in and out of the tip
while air is blowing through it. CAUTION: DO NOT USE PROPANE;
EXPLOSION HAZARD!
Once a year, using a 7/16” wrench and ratchet with an extension,
check that all the bolts on the heater perimeter are tight. This will
prevent propane leaking out the sides and causing internal combustion.
