7. Installation instruction
1) Installation and test operating
a) When BSeries is applied to use, install the hoist to a support structure, switch on it as
the nameplate indicated, and push the button to watch the running direction of load
hook, if its moving follow the button direction, it means the wires are rightly connected
to power supply, otherwise, the connection failure, please correct it by exchanging
any
two wires connection.
b) Before operating a new hoist for its first lifting, it should be operated without load
for 15 minutes to ensure the running is ok, same procedure should be given to a hoist
which has been out of usage for a long time.

space (1mm), then the working space should be adjusted over again, and if
abrasion of friction disc near to the aluminum core, the brake disc should be
replace in time, otherwise, the brake device can be damaged.
c) Gearing: cleaned and grease lubricated (i.e.no.1) every year.
d) Bearing: cleaned and grease lubricated (i.e.no.1) every year.
e) Hooks: to be checked periodically for the deformation and abrasion measurement,
if the wear or deformation measures up 10% of the standard sizes (ref to illustrated
figure), please change the hooks.
f) Hooks: to be checked periodically for the deformation and abrasion measurement,
if the wear or deformation measures up 10% of the standard sizes (ref to illustrated
figure), please change the hooks
3) Repairing warning
Once the hoist damaged or can not be operated normally, shall consult with local supplier
or the designated maintenance, users are not allowed to open or repair the hoist by
themselves.
4) Illustration figure for chain inspection
If chain is abraded over the limit value, which must be replaced with a new one.
