Unsafe Operation Hazard
Except for designated models and
corresponding markets, it is
forbidden to install the anti-pinch
device on other Sinoboom products
or any models in other markets.
Installation instructions
1. Position the support (#4 or #14) at the mounting po-
sition on the platform railing, align the support with
the mounting hole on mounting plate #17, and use
bolts and nuts to secure the support to the platform
railing. Install the support on the other side of the
platform in the same way.
2. Align the foldable plate #3 with the mounting holes
on the left and right supports, tighten it with bolts,
washers and nuts, and install the magnet #18 on
the foldable plate.
3. Then align the support #2 with the mounting holes
on the left and right supports, and make the foldable
plates on both sides of support #2 attracted by mag-
nets, and tighten it with bolts, washers and nuts.
4. Install the cushion block #5 on the left and right sup-
ports in turn, and tighten it with screws, washers
and nuts.
5. Install the travel switch #9 on the left and right sup-
ports in turn, and tighten it with screws and
washers.
6. Install the strobe light #20 on the left and right sup-

of the installation instructions.
Instructions for Use
1. Under normal circumstances, the foldable plates on
both sides of support #2 will be attracted by the
magnets below.
2. Press down the railing of support #2 so that the fold-
able plates on both sides detach from the magnets
and cock up, and the travel switch will be discon-
nected, the left and right strobe lights will flash, and
all functions on the platform controller will be
disabled.
3. Depress the foot switch while flipping the release
switch on the platform controller, and the boom can
be retracted and lowered, and the turntable can ro-
tate slowly.
4. To enable the boom extending and elevating func-
tions, lift the railing of support #2 up until the fold-
able plates on both sides are re-attracted by the
magnets and the strobe light goes out.
