ENGINE OPERATION
DO NOT RUN THE ENGINE AT EXCESSIVE SPEEDS.
The maximum allowable high idle speed for the
POWER-ARC 4000 is 3750 RPM, no load. Do NOT
adjust the governor screw on the engine. Severe per-
sonal injury and damage to the machine can result if it
is operated at speeds above the maximum rated
speed.
Read and understand all safety instructions included
in the Briggs & Stratton Operating and Maintenance
Instructions manual that is shipped with the POWER-
ARC 4000.
BEFORE STARTING THE ENGINE
CHECK AND FILL THE ENGINE OIL LEVEL:
1.
Place the machine on a level
surface.
2.
Open the oil fill plug.
3.
Fill (if necessary) until oil flows out the top of the fill
plug hole.
4.
Replace the fill plug and tighten securely.
CHECK AND FILL THE ENGINE FUEL TANK:
1.
Remove the fuel tank cap.
2.
Fill the tank to allow approximately 1/4
inch (5 mm) of tank space for fuel
expansion. DO NOT FILL THE TANK
TO THE POINT OF OVERFLOW.
3.
Replace the fuel tank cap and tighten securely.
NOTE: The engine will operate satisfactorily on any
gasoline meant for automotive use. A mini-
mum of 87 octane is recommended. DO NOT
MIX OIL WITH THE GASOLINE.
Use clean, fresh, lead-free gasoline. Leaded gasoline
may be used if lead-free is not available. However,
lead-free gasoline leaves fewer combustion deposits
and gives longer valve life. For engine protection from
fuel deposits, use Briggs & Stratton Gasoline Additive,
part number 5041. Purchase gasoline in quantities
that will be used within 30 days, to assure freshness.
NOTE: We DO NOT recommend using gasoline that
contains alcohol, such as gasohol. However,
if gasoline with alcohol is used, it MUST NOT
contain more than 10% Ethanol and MUST be
removed from the engine during storage. DO
NOT use gasoline containing Methanol.
STARTING THE ENGINE
NOTE: Remove all loads connected to the AC power
receptacles before starting the gasoline
engine.
FOR A “COLD” ENGINE:
1.
Open the fuel shutoff valve on the bottom of the
fuel tank.
2.
Place the choke lever in the lowest, downward
position.
3.
Pull slightly on the recoil starter handle
until resistance is felt.
