Distance and blockage conditions, chemicals, etc. If chemicals are
involved, understand their composition, safety precautions, etc., and
contact their supplier if necessary. If necessary, remove facilities such as
water basins that may interfere with the operation of the dredging machine
and damage the wire rope.
3. Choose the right dredging equipment:
Diameter
of dredge
Rotary drill
spring
9.5mm
50-100mm
(3/8in)
12.7mm
50-100mm
(1/2in)
4. Confirm that the machine has been inspected.
5. If necessary, you can lay a protective mat on the ground because the
dredging operation is very dirty.
6. When carrying the machine, use normal routes, ensuring the handles
are upright and securely fastened. If lifting the machine vertically, use
correct posture and movements. If carrying the machine up stairs, be
careful not to fall, and wear appropriate protective shoes.
7. The machine should be two feet away from the inlet. Too long will cause
the cable to twist and tangle. If this is not practical, you can use a pipe of
appropriate size to connect to the inlet, and then the cable will enter the
pipe through the extension tube to clear the pipe . Improper cable
protection measures may cause the cable to twist, tangle or even break, or
injure the operator.
