ation with the Hilti D-LP 15 and D-LP 32 or D-LP 30
hydraulic power units. Use of other hydraulic units for
powering the saw is permissible only when such units
are of a suitable specification and type approved for use
as a power source for hydraulic drilling or sawing equip-
ment.
Flow rate: max. 50 l/min
Optimum operating range: 36 to 50 l/min
Pressure: max. 210 bar
Optimum operating range: 80 to 120 bar

A built-in safety device limits the oil flow rate to the
hydraulic motor to a maximum of 50 l/min., thus limit-
ing the wire speed to a maximum of 27 m/sec.
The operator will notice when the flow rate limiting device
is activated as the drive unit then no longer runs smooth-
ly (audible and visual indication).
CAUTION
Do not, under any circumstances, operate the saw at a
flow rate in excess of 50 l/min.
