2. Care and maintenance
Cleaning
– It is recommended that the electric wall saw is washed
down by spraying it with water after every use.
Caution:
High-pressure or steam cleaning systems
must NOT be used.
Maintenance
– After completing the job, moving parts such as the saw
head locking mechanism or rail supports should be
lubricated with oil spray.
– As temperatures below zero, the cooling water should
be blown out of the electric wall saw after use.
– The DS TS 5-SE requires no other maintenance.

2.2
Carriage roller play adjustment
– Generally speaking, there should be
no play
between
the carriage and the rail but it should not be so tight
as to cause sticking.
– Test for correct adjustment: Hold the DS-CA5-E car-
riage with 1 metre D-R100 SI rail in front of you. The
rail must not run down through the carriage under its
own weight. If necessary, adjust the guide rollers
쐃
as follows: Fasten the rail with the rail supports to the
base material. Without releasing the locking screws
���
, use the 19 mm AF open-end wrench
���
to preten-
sion the guide rollers as required. After adjusting the
rollers correctly, check that the locking screws
���
are
tightened securely. When checking adjustment of the
individual guide rollers to ensure no play, the carriage
should be pushed on the rail with only one pair of rollers
at a time.
Service
We recommend that the DS TS 5-SE electric wall saw is
inspected at a Hilti service after every 100 operating
hours. This will ensure that the saw is ready for use when
needed.
Checks and inspections
The electrical and mechanical safety of the saw system
and its accessories such as the extension cable must be
checked in accordance with national regulations at the
specified intervals.
In EC countries, following the requirements of EN 60204-1,
it is recommended that the checks/inspections listed
below are carried out annually:
– Earth conductor resistance measurement (max. 0.3
ohms)
– Instead of the insulation resistance measurement as
per EN 60204-1, the leakage current during operation
should be measured as possible failure of the insula-
tion can be identified very quickly in this way.
– Earth conductor leakage current (max. 3.5 mA during
operation, machine standing on insulated base)
– Functional test and visual inspection of emergency
OFF, operating controls, indicators, seals, cable, blade
guard and supporting system to identify obvious faults
which could present a hazard.
