| Transmission System | With closed double-loop hydraulic transmission system and planet
decelerator, tension wheel is driven by primary gear. With
inversion, the magnitude of reverse traction force is led by exit
pressure of pump. In tension condition, hydraulic motor rotation is
driven by the tension wheel; the magnitude of tension is controlled
by regulating the motor exit pressure. |

| Storage battery | 6-QA-110(2 sets) |
| Diesel engine starting | 24V electric starting |
Operate Accord to the Followed Order when Starting
1. After fixed the tension machine, open the “power” switch, pull
the start switch to start diesel engine and observe whether the
index on the displays is normal.
2. Put all the control handles in the control box in starting
position, including:
(1) Put engine throttle in minimum position (idle speed).
(2) Rotate the knob “PULLING HANDLE” to median position, that is
position of “TENSION”.
(3) Loosen all the “TENSION REGULATIONT” ” REGULATION OF REEL
WINDER PRESSURE”.
(4) Rotate the knob “BRAKE” to the position of “Brake”.
3. Keep the engine in idle speed for 1-2 minutes after starting and
observe whether the displays of the instruments are normal at the
same time. Pay attention that the index of "BEAKE PRESSURE" can’t
be lower than 1.8MPa or higher than 2.5MPa; Otherwise, it is
necessary to stop the machine for inspection.
4. Within 10 seconds, if the engine failed to start, the knob
should be released immediately and started for a second time after
one minute. If it couldn’t start three times in a row, it should be
stopped and the operators must find out the reasons, debug them and
start later.
5. When delivering under tension, the brake should be released at
first. The method is as following: Rotate "Brake" to "Release"
position, observe whether the readings of "Brake Pressure" are not
less than 3.5Mpa, if the brake pressure had declined, it needs
shutdown inspection.
