METAL CUTTING
See Figure 12, page 15.
NOTE: The jig saw has to be in the no-orbit mode to cut
metals and conduit. Set the orbital adjustment knob to “0.”
Refer to the
Orbital Motion section earlier in this manual
for more details.
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
OPERATION
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.
ADJUSTMENTS
WARNING:
Before performing any adjustment, make sure the product
is unplugged from the power supply. Failure to heed this
warning could result in serious personal injury.
TIGHTENING BASE ADJUSTMENT LEVER
See Figures 13 - 14, page 15.
The base adjustment lever may need occasional
tightening.

Unplug the saw.
 If attached, remove the vacuum attachment.
 Remove the base plate screws and base plate by remov-
ing the four base screws to expose the adjusting nut.
 Release the base adjustment lever by pulling it forward.
 Tighten the adjusting nut 1/4 of a turn in the clockwise
direction.
 Engage the adjustment lever by pushing it back under
the motor assembly and check the base for any move-
ment.
 If the base is still loose, release the adjustment lever and
tighten the adjusting nut another 1/4 of a turn. Repeat
until the base is secure after engaging the adjustment
lever.
 Reinstall the base plate and four base plate screws.
