The machine must stop when changing the line speed.
When the safety cover on the sawing machine is opened, the machine must be shut
down.
When loading, unloading or replacing the saw blade and steel brush, the operator must
stop the machine and wear safety gloves to operate.
When the machine is running, it is strictly prohibited to open any protective cover or
touch the saw blade.
When changing the belt, the operator must stop the machine and then open the motor
cover to change it.
When choosing saw blade, blade line speed and cooling water, please refer to the
instruction manual or related regulations.
Please keep the machine clean and remove iron filings and oil stains from the machine.
Non-professionals are not allowed to carry out maintenance or maintenance work
related to the machine. Power supply must be cut off before maintenance.
The coolant is harmful to the human body, and the operator should pay attention to it
when cleaning or discharging. Coolant should not be discharged directly into the ground,

1.3 Hydraulic oil
Before using the machine, we must have the amount of oil in the tank. If the amount of
oil is not enough, please add hydraulic oil or similar oil until the filter is completely
immersed in the oil.
Take southern weather as an example, use 46# hydraulic oil in summer and 32#
hydraulic oil in winter.
1.4 Cooling water
Before packaging, we have cleaned the cooling water in the sawing machine to keep
the cooling tank dry.
Please add cooling water (5 ~ 8% saponified liquid, the rest is tap water) before using,
and check whether the height of the cooling water exceeds the maximum water level of the
pump. Do not exceed the maximum water level of the pump when adding cooling water
After daily work, the machine should be cleaned to avoid rust; if it is not used for a long
time, the machine should be protected with rust-proof oil.
Warning:
• The cooling pump is forbidden to run without cooling water, otherwise the cooling pump
will be damaged.
• In winter, if the cooling water freezes, do not turn on the machine. Use about 10℃of
warm water to melt before turning on the machine, otherwise the cooling water pump will
be damaged.
1.5 Power supply
①All power distribution should be carried out by professional electricians in
accordance with national power distribution standards.
②When we are going to carry out the work of power distribution, we should
disconnect the external power supply first to achieve the insulation effect. If you just
disconnect the main switch, the line between the incoming line and the main switch is
electrified.

③If you want to connect to the power supply, you should use an appropriate cable to
connect, and make sure that the wire we use is suitable.
④When the machine is installed and connected to the power supply, be sure to
connect the protective grounding wire to the special protective grounding contact of the
machine's electrical box!
⑤When the machine tool needs to be overhauled, be sure to turn off the external
power switch, lock it at the stop position and remove the key to ensure personal and
equipment safety!
