INSTRUCTIONS & PARTS LIST FOR OPERATING
MODEL FN BORING MACHINE, ENGINE CYLINDER
CLEAN MACHINE
Clean the machine thoroughly, removing all dust and grit collected in transit. The rust preventative used on the
machine and all parts may be quickly removed with a cloth dampened in solvent. Clean bottom of machine base in
like manner.
LUBRICATION
TRANSMISSION - A certain amount of oil is left in the transmission after testing. CHECK THE OIL LEVEL BEFORE
OPERATING THE MACHINE. Remove the slot head pipe plug immediately under the shift lever on the handwheel
side of the machine. There should be sufficient oil in the transmission to flow from this hole. If the oil level is not high
enough to flow from this hole, then remove the pipe plug immediately under the front edge of the motor and pour SAE
#30 oil in the upper hole until it runs out of the lower one; then replace both plugs. MAINTAIN THE OIL LEVEL
PROVIDED BY THE PLUG IN THE COVER IMMEDIATELY UNDER THE SHIFT LEVER ON THE HANDWHEEL
SIDE OF THE MACHINE DO NOT EXCEED IT.
MOTOR BEARING AND DRIVE SHAFT PULLEY BEARINGS - This machine is equipped with sealed ball bearings on
the motor shaft which will not need additional lubrication and the drive shaft pulley assembly is, also, equipped with
sealed ball bearings so no lubrication is necessary. Wipe the drive shaft with thin layer of oil to provide lubrication for
the sliding action of the pulley moving up and down the shaft.
OILERS - There are snap lid oilers immediately behind the handwheel and under the front edge of the motor. The
snap lid oilers should be lubricated regularly.
FEEDSCREW - Lubricate the feedscrew occasionally by squirting the oil directly on the threads of the screw. Filling
the ring at the base of the screw will lubricate the thrust bearing.
BORING SPINDLE - The boring spindle is mounted on a pre-packed bearing and a sealed ball bearing so additional
lubrication is not necessary.
MOTOR CURRENT
Be sure the motor is of the proper voltage and cycle for the current available. The motor nameplate will give this
information.
OPERATION OF MACHINE
Before inserting the plug on the motor cord into the outlet, be sure the motor switch is in OFF position. Before turning
the motor on, be sure both levers are in the center or neutral position.
The operating levers on this machine are removable and can be positioned to meet the operator's ease of handling.
The following instructions are written covering the movement of the levers when mounted with the lever on the
handwheel side pointing back towards the motor end of the machine. The lever on the side opposite the handwheel
vertical in neutral position.
