the proper oil level is maintained. Refer to Section 2 for

of continuous operation. Change oil after first five oper­
ating hours and every 25 operating hours thereafter.
B. FILL FUEL TANK
1. Remove fuel tank cap and check fuel level (see
Photo 4-1 or 4-2). Clean area around fuel cap before
removing to prevent the entrance of dust, dirt and mois­
ture.
2. Use clean, fresh, lead-free, automotive gasoline.
Leaded gasoline may be used if lead-free is not avail­
able. (The use of lead-free gasoline results in fewer
combustion deposits and longer valve life.) A minimum
of 77 octane is recommended. DO NOT MIX OIL WITH
