Connect the SR5000 coolant unit to the attachment (35) on the drill by means of its quick-coupling (03) by passing
the hose through the O-Ring (36) so as to support the tap (02).
The use of the lubrocoolant supplied by
Cembre
, in the recommended concentrations, guarantees optimum life
of the cutting tools.
Consumption of the lubrocoolant depends both on the variable degree of opening of the tap (02) and the inner
pressure of the tank: it is therefore advisable to open the tap a little when the tank is at maximum pressure, while
it must be fully opened when the pressure in the tank is low.
When using the coolant system, pay careful attention to the instructions on the tank label.
To fi ll tank with lubrocoolant, turn handle anticlockwise approximately 2 turns to release handle locking mechanism.
Remove handle/piston assembly from tank.
When drilling with a broach cutter, the delivery and shut-off of the lubrocoolant are controlled by the guide
bit; when drilling with a spiral bit, delivery and shut-off of the fl uid must be eff ected manually by operating
the tap (02).
When the tank is not under pressure, check that the maximum pressure valve is screwed right down.
Avoid leaving the SR5000 coolant tank under pressure or exposed to sunlight for long periods of time.
