Preparation for Use

1.
a. Inspection/Check
Inspect the unit thoroughly prior to operation.
(1) Remove blocking, banding, ties, and other securing material.
(2) Inspect exterior for shipping damage such as broken lights, damaged sheet metal, etc.
(3) Open all canopy doors and inspect interior for foreign material such as rags, tools, shipping
papers, etc.
(4) Check fuel, coolant, and oil hoses and connections for visible leaks. Visually inspect the
compartment floor and ground surface under the unit for signs of leakage. If leaks are found,
correct by tightening hose clamps, tube fitting, etc., as required.
(5) Check security of generator set retaining components.
(6) Check the following for sufficient quantity:
a. Fuel
Press lamps button to energize fuel gage when engine is stopped. Fuel is supplied from a
customer-furnished source.
NOTE: For recommended fuel specifications refer to the Cummins Operation and Maintenance Manual
provided with this Hobart manual (OM-2084).
b. Engine coolant
Remove radiator cap to check coolant level. Coolant level should be at the bottom of the filler
neck. See figure 2 for coolant capacities.
CAUTION
NOTE: For antifreeze protection, use a solution of 50% permanent antifreeze (Ethylene glycol) and
50% clean water.
c. Engine lubricating oil level
The oil gage rod (See Fig 1) has "H" high mark and "L" low level marks to indicate the
operating lubrication oil supply. Oil level should be kept as near the high mark as possible,
without going over it. See figure 2 for oil capacity specifications.
CAUTION
See the Cummins Operation Maintenance Manual for oil recommendations.
d. Check Batteries
Inspect the batteries for proper connection of the terminals and also check the electrolyte
level (if possible). Service or replace if necessary.
November 27/1997
BE SURE the cooling system antifreeze solution is adequate to protect below
lowest temperature expected.
NEVER operate the engine with oil level below the "L" level mark or above the
"H" level mark.
