METAL CUTTING
See Figure 14.
NOTE: The jig saw has to be in the no-orbit mode to cut met-
als and conduit. Set the orbital adjustment knob to “0.”
Many kinds of metals can be cut with the saw using a
metal blade (not included). Be careful not to twist or bend
the blades.
Do not force. If the blade chatters or vibrates
excessively, use a finer-tooth metal-cutting blade. If blade
heats excessively, use lower speed. If blade teeth become
filled or clogged when cutting soft metals, such as aluminum,
use a coarser-tooth blade or lower speed. We recommend
use of lubricant when cutting metals to keep blades cool,
increase cutting action, and prolong blade life. Clamp the
work firmly and saw close to the clamping point to eliminate
any vibration of the work being cut.
When cutting conduit, pipe, or angle iron, clamp work in a
vise if possible and saw close to the vise. To cut thin sheet
materials, “sandwich” the material between hardboard or ply-
wood and clamp the layers to eliminate vibration and material
tearing. By doing this, the material will be cut smoothly. Lay
out your pattern or line of cut on top of the “sandwich.”
NOTE: When cutting metal, keep exposed portion of saw
bar clean and free of metal chips by wiping frequently with
an oily cloth. Use extreme caution in disposing of oily cloth
after completion of job to prevent potential fire hazard.
