WELDING OUTPUT CABLES
With the engine off, connect the electrode and work
cables to the studs provided. These connections
should be checked periodically and tightened if neces-
sary. Loose connections will result in overheating of
the output studs.
When welding at a considerable distance from the
welder, be sure you use ample size welding cables.
Listed below are copper cable sizes recommended for
the rated current and duty cycle. Lengths stipulated
are the distance from the welder to work and back to
the welder again. Cable sizes are increased for
greater lengths primarily for the purpose of minimizing
cable voltage drop.

ANGLE OF OPERATION
Internal combustion engines are designed to run in a
level condition which is where the optimum perfor-
mance is achieved. The maximum angle of operation
for the engine is 15 degrees from horizontal in any
direction. If the engine is to be operated at an angle,
provisions must be made for checking and maintain-
ing the oil at the normal (FULL) oil capacity in the
crankcase in a level condition.
When operating at an angle, the effective fuel capacity
will be slightly less than the specified 9 gallons.
LIFTING
The ZR-8 weighs approximately 575 lbs.(261K) with a
full tank of gasoline. A lift bail is mounted to the
machine and should always be used when lifting the
machine.

WARNING
• Lift only with equipment of
adequate lifting capacity.
• Be sure machine is stable
when lifting.
• Do not lift this machine using
lift bale if it is equipped with a
heavy accessory such as trail-
er or gas cylinder.
FALLING
• Do not lift machine if lift bale is

cause injury.
• Do not operate machine while
suspended from lift bale.

HIGH ALTITUDE OPERATION
At higher altitudes, Welder output de-rating may be neces-
sary.
For maximum rating, de-rate the welder output 3.5% for
every 1000ft. (305m) above 3000ft. (914m).
If operation will consistently be at altitudes above 5,000 ft.
(1525m), a carburetor jet designed for high altitudes should
be installed. This will result in better fuel economy, cleaner
exhaust and longer spark plug life. It will not give increased
power. Contact your local authorized engine service shop
for high altitude jet kits that are available from the engine
manufacturer.
CAUTION
Do not operate with a high altitude jet installed at alti-
tudes below 5000 ft. This will result in the engine run-
ning too lean and result in higher engine operating
temperatures which can shorten engine life.

Muffler Relocation
WARNING
•
Shut off welder and allow muffler to cool before
touching muffler.
-------------------------------------------------------------------------------
The ZR-8 is shipped with the exhaust coming out on the left
side. The exhaust can be changed to the opposite side by
removing the two screws that hold the exhaust port cover in
place and installing the cover on the opposite side.
(Operating the ZR-8 without the cover in place will result in
a higher noise level and no increase in machine output.)
