Startup
Loss of Prime to Pump
Introduction of air into the pump, either by changing
fluids or due to a suction leak, may result in the loss of
prime to the pump. If the pump loses prime, no fluid is
pumped.
To prime the pump, relieve the pressure on the system
by opening the drain valve and following the instruction
on Prime the pump, page 10.

Maintenance

For detailed engine maintenance and specifications,
refer to the separate engine manual, supplied.
WEEKLY: Check the level of the TSL in the displace-
ment pump packing nut. Fill the nut, if necessary. Keep
TSL in the nut to help prevent fluid buildup on the
piston rod and premature wear of the packings.
Monthly: Remove the front cover (9) and fill the
cavity in the connecting rod with non-detergent motor
oil 1/4 in. below the surface. See Fig. 4.
AFTER EACH 100 HOURS OF OPERATION:
Change the oil. Refer to the engine manual for addi-
tional maintenance instructions.
SPARK PLUG: Use only an (NGK) BPR6ES or a
(NIPPON DENSO) W20EPR-U plug. Gap the plug to
0.028 to 0.031 inch (0.7 to 0.8 mm). Use a spark plug
wrench when installing and removing the plug.

face with non-detergent
