Injection method for drill hole depth
> 250 mm or overhead application
Assemble mixing nozzle HIT-RE-M, extension(s) and piston plug
HIT-SZ.
For combinations of several injection extansions use coupler HIT-VL
K. A substitution of the injection extansion for a plastic hose or a
combination of both is permitted.
The combination of HIT-SZ piston plug with HIT-VL 16 pipe and then
HIT-VL 16 tube support proper injection.

For overhead installationthe injection is only possible with the aid of
extensions and piston plugs. Assemble HIT-RE-M mixer,
extension(s) and appropriately sized piston plug. Insert piston plug to
back of the hole and inject adhesive. During injection the piston plug
will be naturally extruded out of the drill hole by the adhesive
pressure.
After injecting, depressurize the dispenser by pressing the release
trigger. This will prevent further mortar discharge from the mixing
nozzle.
