Note：CT420S parameters are based on ambient temperature 25℃. In
a low-temperature environment, the load and endurance will be
reduced. If the low-speed mode is started, the endurance will be
reduced accordingly. This product is recommended to be used within
1000 meters above sea level. It is recommended to use under ambient
humidity range of 45%-85% (no frost or snow).
WARNING ：The center of gravity for the cargo should be
located in the center of the loading board. If the center of gravity of the
cargo exceeds the loading board, it should not be transported by using
the CT420S.

3 Operation
Note—Please put the machine in the environment without
freezing(above 0 ℃) before initial operation!
Warning——Only trained person can operate CT420S.
Warning——Pilot operation must be carried out with no load and
in low speed mode！
Warning——The goods must be fastened with straps!
Warning——Practice operating the machine with cargo of 50-
100 kg until you are fully skilled in controlling the machine.
Warning——When going up and down the stairs, under the non-
automatic adjustment mode of loading board, pay attention to the
center of gravity for the goods to ensure the load balance!
Warning—— Operate it with two hands! Especially when
approaching the last step upward and the first step downward.
Warning——When the slope of the ground is bigger than 5°, it is
forbidden to use the flat ground model by using the caster to move!
Warning——When the machine is in operation, do not place your

13
body parts close to the mechanical positions such as the track, the
loading board and the cover, otherwise personal injury may occur!
Warning——Different goods have different centers of gravity.
For special goods (such as oversize, the center of gravity is biased to
the outside of the loading board, etc.), manually adjust the tilt angle of
the loading board to ensure safe operation!
3.1 Check Before Using CT420S
Warning
Stop operation when the following issues occur and contact
manufacturer or local dealer for CT420S repair.
（1）The battery has been fully charged, but the hand-held controller
