Which Blade to USE, USE of Lubricants | Porter-Cable 7724 manual

WHICH BLADE TO USE

In general, select a blade which will allow at least two teeth to be engaged in the material thickness. The thinner or the harder the material, the finer the blade teeth. The thicker or the softer the material, the coarser the blade teeth. The hi-speed steel blades stay sharp longer than alloy steel blades.

USE OF LUBRICANTS

NEVER USE LIQUID COOLANT WITH YOUR BAND SAW. Damage to the blade guide bearings or rubber tires on the pulleys may result.

LIQUID COOLANTS CAN INCREASE THE RISK OF ELECTRIC SHOCK. Use only stick wax to lubricate the blade.

Porter-Cable’s “Lube Wax” is available as an accessory and is recommended when cutting aluminum, brass and thick materials. Cast iron should be cut dry.

With the saw running, apply the wax momentarily to both sides of the blade. Reapply wax intermittently as needed.

EXERCISE EXTREME CARE TO PREVENT HANDS FROM CONTACTING THE BLADE.

After prolonged cutting, the wax will cling to the pulleys of your BAND SAW. This does not affect the operation of the machine. All that is necessary is to disconnect the machine from the power source and wipe the wax from the pulleys.

TO CHANGE SAW BLADES

DISCONNECT TOOL FROM POWER SOURCE.

TO REMOVE BLADE – Turn handle (A), Fig. 2, clockwise to release tension on the saw blade. Remove the blade, first from the pulleys and then from the blade guide.

Before installing a blade, clean chips and wax, which may have accumulated on blade guides and pulley tires. TO INSTALL BLADE – install blade in blade guides and then position on pulleys. MAKE SURE TEETH ON LEFT SIDE OF MACHINE POINT TOWARD THE REAR OF THE MACHINE. See Fig. 3.

Turn handle (A), Fig. 2, counterclockwise as far as it will go. This places tension on saw blade.

Start and stop saw two or three times to seat blade on pulleys.
