non-foaming hydraulic oil, such as Mobil DTE 10 or equivalent.
The power down feed option, used in conjunction with the power vise option, changes a manual
saw into a semi-automatic saw. These options will increase productivity and reduce operator
fatigue. The power down feed option cannot be retrofit to machines with serial number 11940491
and prior in the field. This option can be used on machines with or without the power vise option.
CAUTION : ALWAYS DISCONNECT THE AIR SUPPLY BEFORE REMOVING THE
FILLER PLUG FROM THE RESERVOIR. IF THE FILLER PLUG IS
REMOVED WHILE THE MACHINE IS CONNECTED TO THE AIR
PRESSURE, THE FLUID IN THE TANK WILL BE PURGED THROUGH
THE OPENING UNDER PRESSURE.
