PLANNING THE CUT
The following steps are recommended to maximize cutting efficiency, productivity and
assure safety:
• Outline the cut with a permanent marker.
• Layout concrete anchor marks 3
1
⁄4 inches (8.3 cm) inside each cut line.
• Set the anchors. Caution: The anchor bolts cannot protrude out of the wall more than 3/8 inches
(1 cm) or interference with the SpeedHook® mounting bracket (on the saw) can occur.
• Cutting sequence: Always start with the right-hand side cut first, then the bottom and then the
top. Save the left-hand side cut for last. Using this sequence you will only need to reverse the
axle for the last cut.
• Be sure cut concrete cannot fall and injure operator or bystanders.
• Check for live electrical wiring near cutting areas or in the concrete to avoid electrocution which
can result in death or serious injury.

MOUNTING THE SPEEDHOOK
TO WALL
• Loosely attach the rail to the wall so that the horizontal and vertical adjustments can be made.
• Position the rail so that the scribe line near the bottom of the rail is where you want the cut to end.
• Position the outside of the rail exactly 1½ inches (3.8 cm) from the center of the cut line and
securely tighten the anchors, using thick fender washers.
• Do not flex SpeedHook
®
to the wall when gaps exist. Instead, shim gaps between SpeedHook®
and wall.
MAKING THE CUT
• Engage the axle into the hook of the rail near the beginning of the cut.
• Rotate lever arm to engage the cams, locking the axle firmly in place.
• Rev up the saw to full RPM.
• Slowly rotate the saw into the wall making sure the cut starts exactly on the cut line.
• As the saw approaches the end of its rotation, keep the chain running and index the next set of
hooks. It is easier to index if the saw has not reached a full 90 degrees.
• Leave the water on and run the saw for 15 seconds with bar tip down to flush slurry and debris
from the system.
®
• Wash concrete slurry from the saw assembly and SpeedHook
.
• Spray entire SpeedHook®, saw, chain, bar and drive sprocket with a lightweight penetrating oil.
This will minimize rust and reduce slurry build-up on saw assembly.
TIPS FOR CUTTING STRAIGHT
• MOUNTING - Ensure the SpeedHook
®
rail is securely fastened to the wall, and that the patent
number stamped on centerpiece is facing away from wall. Ensure mounting anchors have not
loosened from the concrete. If the rail becomes loose, SpeedHook
®
will not cut straight.
• SPACERS - Use 2 to 3 inch (5 to 7 cm) diameter washers to space the rail off the wall especially
when the wall is not perfectly flat. This will reduce warping.
• ANCHORS - Only use anchors approved for mounting wall saws.
• SHORT BAR - Always use the shortest bar possible to cut through the wall. Long bars are
susceptable to deflection, especially when starting the cut.
• STEP-CUT - In hard materials or walls over 8 inches (20 cm) thick, cut as much as you can with
a short bar then switch to a longer bar to finish the cut.
• STARTING THE CUT - Accurately space the rail from the cut and start the cut exactly on
the cut line.
• LONG CUTS - If cut exceeds 42 inches (105 cm), it is possible to stack SpeedHook® rails end to
end.
• FEED PRESSURE - Start the cut using light feed pressure. Be patient, let the saw and chain do
the work. Excessive feed force will cause the bar to deflect and cut crooked.
• AXLE ENGAGEMENT - Keep both bearing surfaces of the axle engaged into the back of the
hooks while cutting. Rotate lever arm 90 degrees to the wall surface until the cams are engaged,
forcing the axle toward the back of the hooks. Support the hydraulic hoses when cutting
horizontally.
• AXLE CAMS - To maximize the life of the cams, avoid engaging the cams against the large
Speedhook® rail anchor washers. The washer's sharp edge will gouge the cams, reducing their
effective life. If possible, avoid the hook that causes interference between the cams and anchor
washers.
• DRESS BAR RAILS - At the first sign of a crooked cut, flip the guidebar over (it's reversable).
Dress the guidebar rails on a belt sander to make the rail height on each side even again.
• UPGRADE SPEEDHOOK - To help cut straighter, with less physical effort, upgrade earlier
