HYDRAULIC OIL AND CUTTING FLUID
The S-25A bandsaw is supplied with Valvoline 150-46 hydraulic oil. If it is necessary to change the oil to a
different brand see the HYDRAULIC SECTION for an equivalent grade oil.
No cutting fluid is supplied with the machine. There are two types of coolant available:
- oil based; dilute 1:10 ratio
(one part concentrated coolant to 10 parts water)
- synthetic; dilute as recommended by the manufacturer.
WIRING CONNECTIONS
After the machine is levelled and anchored the necessary power hook-up needs to be performed. In order to
provide safe operation as well as to prevent potential damage to the machine, only qualified personnel should
make the connections.
BEFORE START-UP THE FOLLOWING TWO POINTS SHOULD BE CHECKED FOR
-signs of damage that may have occurred during shipping to the electrical cables and the hydraulic hoses.
-the hydraulic oil level is between the upper and lower lines on the level gauge (see SECTION 3 pg. 3.4).
As supplied, the machine is set to run on three phase voltage as indicated on the serial plate and voltage
label.
Power connection to the machine is made to L1, L2, L3 terminals at the junction block inside the control box
Fig.1-9. During the initial hook-up it is very important to check that the phase order is correct. This is indicated
by the hydraulic pressure gauge registering a pressure rise Fig. 1-10 and the blade running in a counter
clockwise direction. If the hydraulics do not register an immediate pressure rise, shut the hydraulics off and
change the phase order.
ATTENTION: Running the hydraulics "backwards" can damage the hydraulic pump.
