RotoZip RZ2000 - Manual (Page 6)

Do not run the tool while carrying it at your
side. Accidental contact with the spinning
wheel could result in serious personal injury.
Never lay the tool down until the motor has
come to a complete standstill. The spinning
wheel can grab the surface and pull the tool
out of your control.
Do not use the Zipmate near flammable
materials. Sparks from the wheel could ignite
these materials.
Never cut or attempt to cut magnesium
with this attachment. The dust generated
when cutting magnesium is highly flammable
and may be explosive under certain conditions.
Regularly clean the tool’s air vents by
compressed air. Excessive accumulation of
powdered metal inside the motor housing may
cause electrical failures.
Causes and Operator
Prevention of Recoil:
Recoil is a sudden reaction to a pinched,
bound or misaligned rotating wheel. The wheel
may stall and cause an uncontrolled tool to
back out of the kerf toward the operator when
the tool is in the “fire forward” position, if the
tool is set in the “reverse fire” position the tool
may tend to walk away from the operator. The
rotation direction arrow located on the back
side of the guard can be used to identify the
“fire forward” and “reverse fire” positions. The
attachment is in the fire forward position when
the directional arrow points toward the
operator, and it is in the reverse fire position
when the arrow is pointing away from the
operator.
If an abrasive wheel or diamond wheel
becomes twisted or misaligned in the cut, the
side of the wheel that is entering into the
material can dig into the top surface of the
material causing the wheel to climb out or
recoil out of the kerf either toward or away
from the operator, depending on the fire
forward or reverse fire orientation.
Abrasive wheels may also shatter under these
conditions causing pieces or fragments to
strike or impale the operator and bystanders.
Recoil or shattered wheels are the result of
tool misuse and/or incorrect operating
procedures or conditions and can be avoided
by taking proper precautions as given below:
Maintain a firm grip with both hands on the
tool handles and position your body and
arm to allow you to resist recoil forces.
Recoil forces can be controlled by the
operator, if proper precautions are taken.
When wheel is binding, or when
interrupting a cut for any reason, slowly
ease the wheel out of the material while
maintaining a firm grip on the tool and
auxiliary handle with both hands.
Investigate and take corrective action to
eliminate the cause of wheel binding.
When restarting a tool in a workpiece,
center the wheel in the kerf and check that
the sides of the wheel are not engaged into
the material. If wheel is binding, it may walk
up or recoil from the workpiece as the tool is
restarted.
Support large panels to minimize the risk of
wheel pinching and recoil. Large panels tend
to sag under their own weight. Supports must
be placed under the panel on both sides, near
the line of cut and near the edge of the panel.
Use extra caution when making a “Pocket
Cut” into existing walls or other blind
areas. The protruding wheel may cut objects
that can cause recoil.
Jigsaw Handle Attachment Safety Rules
Do not use any router bit
with a cutting diameter larger
than 1/4" with the Jigsaw Handle Attachment.
When using a 1/4" shank bit
or any router bit with the
Jigsaw Handle Attachment, the collet nut
must be tightened using the supplied wrench.
Finger tight is not sufficient for router bits.
Indicate direction of rotation
of the bit. When viewing
from above, DOR is CW. When viewed from
the end of the bit, DOR is CCW.
Before doing any work with
the Jig Saw Attachment,
tighten the depth adjust screw tightly.
