– After a guide cut
has been made with the saw arm in the trailing position, subsequent cuts can be made
with the arm in the leading position
or trailing position
, as required.
10.6 Ending the sawing procedure
– When the concrete has been cut through, raise the blade out of the kerf while it is still rotating, turn the water
off, stop the motor and bring the saw head to a suitable position on the rail.
– Set all knobs on the remote control unit to the “0” (neutral ) position.
– Switch off the hydraulic unit at the on/off switch (turn the switch to position (2) = “0”)
– The on/off switch (1/2) must also be returned to the “0” position if the emergency OFF button has been used
to switch off the hydraulic unit.
11. Dismantling the saw system
11.1 Dismantling the saw system
– Secure the block of concrete you have cut. Use steel wedges when necessary.
– Clean the equipment by spraying with water. Dry the parts with a cloth.
– Remove the blade guard, blade and other modules (following the assembly instructions, but in the reverse order).
– Secure the block of concrete or carefully withdraw it from the hole and make arrangements for its transport.
– Cordon off the opening so that is presents no hazard to third parties.
12. Care and maintenance
12.1 Maintenance of the hydraulic unit - see section 9
– Change the oil every 12 months. The service reminder sticker on the cover of the hydraulic unit indicates when
the next service is due.
– High-pressure or steam cleaning systems should NOT be used to clean the hydraulic unit.
12.2 Maintenance of the DS-TS 30 saw head
– The saw head basically requires no maintenance (Exception: lubrication of the cam-action roller bearings at
the grease nipples). We recommend that it is serviced every 12 months. The service sticker on the blade guard
holder indicates when the next service is due.
– The hydraulic couplings should be cleaned daily and checked to ensure ease of operation.
– The guide rollers and cam-action rollers should be kept clean and lubricated with Hilti oil spray.
– Clean the gear change mechanism at the saw blade spindle at weekly intervals and lubricate it with Hilti oil spray.
– These instructions apply to all Hilti saw heads.
12.3 Cleaning with high-pressure and steam cleaning systems
– If a cleaning system of this kind is used to clean the saw head, do NOT direct the jet into openings and at the seals.
12.4 Maintenance of the other saw system modules
– The D-R..L rails have a transparent anodised finish and can be washed very easily. The internal taper on the
rails should be cleaned particularly carefully with a cloth and then lubricated with Hilti oil spray.
– The other modules such as the blade guard, rail supports etc. basically require no maintenance. We recom-
mend, however, that they are cleaned each time immediately after use.
– The hydraulic hoses, and the couplings in particular, should be cleaned daily and checked to ensure ease of
operation.
