GAW-135H DC WELDER/AC GENERATOR — OPERATION MANUAL — REV. #1 (06/23/04) — PAGE 29
General Inspection
At least daily or prior to each use, the generating set should
be cleaned and inspected for deficiencies. Check for loose,
missing or damaged nuts, bolts or other fasteners. Also check
for fuel or oil leaks.
Engine Side
(Refer to the Robin Engine Instruction Manual)
Check Oil Level
Check the crankcase oil level prior to each use, or when the
fuel tank is filled. Make sure the generating set is level. The
oil level must be between the two notches on the dipstick.
Changing Oil
Change oil after the first 20 hours of operation. Drain and
refill the engine crankcase every 50 operating hours or once
a week thereafter. Drain crankcase oil into a suitable container
while engine is still warm. Replace the drain plug tightly. Add
oil through the filler hole.
Air Cleaner
Every 50 hours: Remove air cleaner element (std. or heavy
duty types), and wash in kerosene or liquid detergent and
hot water. Wrap foam element in a cloth and squeeze dry.
Wipe heavy duty paper element dry with toweling. Saturate
element with kerosene; squeeze excess from foam element.
Wipe excess from heavy duty paper element.
GAW-135H — MAINTENANCE
Service Daily
If engine is operating in very dusty and dry grass conditions.
A clogged air cleaner will result in high fuel consumption,
loss of power and excessive carbon buildup in the
combustion chamber.
Cleaning the Fuel Strainer
Clean the fuel strainer if it contains dust or water. Remove
dust or water in the strainer cap and wash it in gasoline.
Securely fasten the fuel strainer cap so that fuel will not
leak. Check the fuel strainer every 200 hours of operation or
once a month.
Spark Plug
Remove carbon build-up on the spark plug (Figure 25) with a
wire brush. Set the spark plug gap to 0.6—0.7mm (0.024-
0.028 inch). Tighten with a spark plug socket wrench. Clean
the spark plug every 50 operating hours or once a week.
