BATTERY FILLING AND SERVICE INSTRUCTIONS
TO GAIN ACCESS TO BATTERIES:
Remove the lower rear panel (radiator end).
NOTE: Batteries must not be filled or "Topped Up" whilst
they are in normal operating position. (Remove them
from the machine first).
COMMISSIONING AND RECHARGING
INSTRUCTIONS
1 - Remove the battery from the machine before filling or
recharging.
2 - Remove and retain vent plugs.
3 - Fill each cell of the battery to the top of the separators with
the correct grade electrolyte* (ie. 1.260 specific gravity).
Using higher or lower specific gravity electrolyte than
recommended can impair the battery performance.
4 - Boost charge the battery at 15amps until the specific
gravity of the electrolyte is 1.250 or higher and the
electrolyte
temperature
CONDITIONS MUST BE MET.
If electrolyte bubbles violently while charging, reduce the
charging rate until the excessive bubbling action subsides,
then continue until both of the above conditions are
achieved.
If the ambient temperature is 10˚C or less, it is imperative
that the above instructions be followed.
5 - After boost charge check level of electrolyte in all cells. Add
additional electrolyte to bring level to that shown on
labelling. DO NOT OVERFILL. After the battery has been in
service, add only approved water. DO NOT ADD ACID.
NB. Depending on the age of the dry charged battery
correct activation may take up to 48 hours.
6 - Disconnect the battery from the charging source and refit
the vent plugs ensuring they are screwed or pushed all the
way home.
7 - Wash away any spilt electrolyte with water and dry the
battery completely before installing it into the machine.
INSTALLATION
1 - Inspect the battery tray and remove any foreign objects that
may be present.
2 - Place the battery in the tray.
3 - Connect the positive battery lead (marked with a red band),
then connect the negative lead.
NB. Always connect the negative lead last when installing a
battery.
4 - Refit the battery hold-down assembly. Do not overtighten
this assembly as battery case damage is possible.
BATTERY MAINTENANCE
1 - Keep the electrolyte levels about 6mm above the plates and
separators.
2 - Keep terminal posts free of corrosion.
3 - Keep battery clean and dry.
4 - Do not leave machine switched on without the engine
running as this will discharge the battery.
5 - Do not fast charge any battery over 18 months old.
6 - Never add acid to a battery unless it has been lost through
spillage.
*NOTE: To prevent acid surge from bottle when filling,
pierce a small hole in the top of the acid bottle to allow
bottle to "breathe".

IMPORTANT SAFETY INSTRUCTIONS
• Battery electrolyte contains SULPHURIC ACID which
is corrosive to skin and clothing.
• Batteries also contain EXPLOSIVE GASES.
• Do not do anything to cause sparks near the battery.
Keep naked flames and cigarettes away from batteries.
• If acid contacts eyes or skin FLUSH IMMEDIATELY with
large quantities of CLEAN DRINKING WATER.
• IN CASE OF ACID CONTACTING THE EYES,
IMMEDIATELY FLUSH WITH WATER FOR 20 MINUTES
AND CONSULT A DOCTOR.
• After use wash out empty electrolyte bottles with water
and dispose of carefully - do not use empty electrolyte
bottles for any other purpose.
• ALWAYS KEEP BATTERIES AND ELECTROLYTE OUT
OF REACH OF CHILDREN.
• DISPOSE OF OLD BATTERIES CAREFULLY.
• WHEN
CHARGING,
VENTILATION TO ALLOW THE SAFE ESCAPE OF
EXPLOSIVE GASES.
WELDER MAINTENANCE
Whenever possible have a qualified electrician do the
needed electrical maintenance and trouble shooting
work. Turn the engine off when working inside the
machine.
ROUTINE MAINTENANCE
1. AFTER 25 HOURS OF USE OF YOUR NEW
WELDER, CHECK ALL NUTS AND BOLTS FOR
TIGHTNESS. Thereafter check all nuts and bolts
every 1000 hours of operation.
2. Blow out the welder and controls with an air hose at
least once every two months. In particularly dirty
locations this cleaning may be necessary once
every week. Use low pressure air to avoid driving dirt
into the insulation.
3. Current Control reactor brushes are silver graphite
and should not be greased. Keep the contacts clean.
4. Keep electrode and work connections tight.
BEARINGS
Your welder is equipped with a double-shielded ball
bearing having sufficient grease to last indefinitely under
normal conditions. Where the welder is used constantly
or in excessively dirty locations, it may be necessary to
add 15 grams of grease per year.
When greasing the bearing, keep all dirt out of the area.
Wipe the fitting completely clean and use clean grease
and equipment. More failures are caused by dirt
introduced while greasing than from insufficient grease.
COMMUTATOR AND BRUSHES
The generator and alternator brushes are properly
adjusted when the welder is shipped. They require no
particular attention. DO NOT SHIFT THE BRUSHES or
adjust the rocker setting.
Periodically inspect the commutator and brushes.
