Care And Maintenance - Hilti D-LP 15 Operating Instructions Manual

CAUTION
Disconnect the supply cord plug from the power outlet.
CAUTION
Keep the machine, especially its grip surfaces, clean
and free from oil and grease. Do not use cleaning
agents which contain silicone.
11.1
Cleaning the equipment
■ We recommend that the most important parts of the
saw system are cleaned quickly between each saw
cut. Simply use the water hose to wash down the
saw head, rails, blade guard and saw blades.
■ All switches and controls must be set to the "off" or
neutral positions and the power supply cable
unplugged before beginning thorough daily clean-
ing.
■ Immediately after finishing work each day, use the
water hose and a brush to wash down the entire set
of equipment thoroughly, paying particular attention
to the parts mentioned above. Cleaning should be
planned as a part of the working procedure. This will
ensure that the equipment can be operated efficient-
ly each day.
Cleaning with high-pressure or steam cleaning sys-
tems
If a cleaning system of this kind is used to clean the saw
head, do not direct the jet into openings or at seals.
11.2
Maintenance of the D-LP 15 hydraulic unit
■ Check the oil level of the hydraulic unit at weekly
intervals. Top up if necessary with type HVLP 46
hydraulic oil.
■ Changing the oil and filter: Change the hydraulic
oil (type HVLP 46) and filter after approx. 200 oper-
ating hours or once a year. The service sticker on
the cover of the hydraulic unit indicates when the
next service is due.
■ Should the unit seem to lack power, it can be
checked on the spot by a Hilti specialist if necessary.
■ Do NOT use a steam cleaning system or water jet to
wash down the hydraulic unit.
■ Operation in winter or at low temperatures: When
cold, the hydraulic unit should be allowed to run for a
few minutes, with water flowing, until it has warmed
up.

11. Care and maintenance

■ Do not operate the hydraulic unit without cooling
water connected. Always keep the water running
when operating at temperatures below zero. Discon-
nect the water supply to the hydraulic unit and the
water system hose when work is finished. The
hydraulic unit then drains itself automatically. Use
only water hose couplings of the free-flow type
for the water supply to the hydraulic unit.
■ If an electric generator is used to power the D-LP 15
hydraulic unit, we recommend an output of at least
30 kVA. The generator must be earthed.
11.3
Maintenance of the DS-TS 22 saw head
■ The saw head basically requires no maintenance. We
recommend annual servicing.
■ 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.
■ Check occasionally to ensure there is no play
between the carriage and the rail and adjust correct-
ly if necessary.
■ Use Hilti oil spray to protect and lubricate the gear
change mechanism. Keep the mechanism clean and
ensure that it operates smoothly.
11.4
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 sup-
ports, etc., basically require no maintenance. Never-
theless, we recommend immediate cleaning each
time after use.
■ The hydraulic hoses should be cleaned daily, paying
particular attention to the couplings to ensure ease of
operation.
11.5
Service and repair
■ Malfunctions are unlikely when the equipment is
kept clean and lubricated. Lack of cleaning and
incorrect operation may lead to malfunctions.
■ Additional parts (spare parts) are available from Hilti
service when required and, under normal circum-
stances, can be fitted on site by the operator him-
self, by a Hilti specialist or Hilti repair mechanic.
