start of tool operation. Allow oil to
warm to operating temperature.
Actuating tool intermittently will
reduce time required to warm oil to
an efficient operating temperature.
Check pump suction line for
damage or loose clamps. Tighten
clamps or replace components if
necessary. Fill reservoir.
Check for dirt or gummy deposits.
Clean components. Check for worn
or damaged components. Replace
components.
