10. Setting up, checking and operating the D-LP 30 (LP 20) / DS-TS 30
(-54 and 55) hydraulic saw system
10.1 Points to check before beginning sawing
– The rail supports and rails must be aligned and fastened correctly (all screws fastened securely).
– The saw head must be mounted without play, the eccentric rollers engaged and the correct gear selected.
– The hydraulic hoses and water hoses must be laid out, connected correctly and the locking sleeves engaged.
– A suitable saw blade must be mounted in the correct direction of rotation, the mounting screws tightened
firmly and the blade guard mounted and secured.
– The electric power must be connected and ready, water running, emergency OFF buttons disengaged (pulled
out) and the operating controls on the DS-CB 3 / CB 4 electric remote control unit set to the "O" (off) or neu-
tral position.
10.2 Operation of the D-LP 30 (LP 20) using the DS-CB 3/CB 4 remote control
The DS-CB 3 / CB 4 electric remote control unit provides the operator with the optimum means of control at all
times. It is quick and convenient and thanks to its 10 metre long cable (additional 10 metre extension cable avail-
able, item no, 258301/1), every operation can be supervised and controlled from the ideal, safe position.
Pos. 1: Electric motor ON (0 Í I Í start Í release I)
Pos. 2: Electric motor OFF (I Í 0)
Pos. 3: Plunge movement (right/left)
Pos. 4: Advance (right/left or up/down)
Pos. 5: Speed of advance for controls (3) and (4)
Pos. 6: Max. power in amps, depending on mains supply
Pos. 7: Flow rate 0–100 l/min. (motor unit / blade r.p.m.)
Pos. 8: Emergency OFF button
Note: The DS-CB 3 remote control unit has no emergency OFF, but all
other functions are the same as with the DS-CB 4 remote control unit.
Procedure
1. Adjust the current (6) to a value between 32 amps and approx. 55 amps
(maximum), depending on the mains supply available on the jobsite. This
limits the current input, ensuring that the mains supply is not overloaded,
thereby causing the fuse to blow during operation. This knob also regulates
feed/advance sensitivity. When this knob is turned to the right as far as it will
go, the system operates too abruptly, i.e. the advance movement is too quick
and the saw blade tends to stall.
When connected to a 63 amp mains supply, DO NOT turn this knob to
the right as far as it will go.
2. Knobs (3), (4), (5) and (7) should be set to "0" (neutral position). Switch on the
electric motor (2/1) and check that the hydraulic unit switches from star to
delta (switching mechanism can be heard to operate, duration approx. 2–5
seconds).
3. Use the potentiometer (7) to adjust the oil flow rate (blade spindle drive
motor) according to the blade diameter used and characteristics of the
material to be cut (see section 6.2).
4. Begin the plunge movement by rotating knob (3) and holding it in position
until the desired cutting depth is reached. The speed of the plunge move-
ment is controlled by knob (5).
