Model 900 Operation
The TRAMAC Model 900 in the standard version
must not be used for underwater work, even for
very short periods of time. If the chamber
between the piston and the tool fills with water
when the piston strikes, the water will not be
evacuated fast enough and a considerable
pressure rise will then occur which and destroy
the piston seal (with a risk of piston seizure).
Compressor Pressure: Pressure from the compressor must be at least 22 psi above the water pressure
at the working depth. Water pressure equals 14.5 psi for every 30 feet of depth. Through the first 30 feet
36.5 psi of air pressure is required.
Tool Life: TRAMAC working tools are made from a special steel far superior to any tool steel commercially
available. Unlike other tools on the market, our steel is hardened all the way through - no thin shell of hard
steel which wears quickly. When the tools lose their edge, either at the tip or on the sides, it is possible to
sharpen them without repeating heat treatment, using one of the following methods:
A) With a milling or planning machine for chisels and spades, or with a lathe for the moils and blunt tools.
These operations must be completed using an adequate type of hard metal tool.
B) By sharpening: This operation must be performed using a coolant to prevent the tool from overheating.
As a general rule, never let the tool cool quickly or suddenly, even when it is used with the breaker.
Dipping the tool into water when it has been heated in the course of work or leaving it in the snow in the
winter will result in a drenching effect on the tip or cutting bit and increases the risk of breakage.
Tools are covered by TRAMAC against metal defects (very uncommon). It is not unusual that some
operations (working at angles or blank firing) lead to tool breakage, including inside the chuck housing.
The use of after market tools will void your warranty for any claim related to parts in contact with the tool
(including the main piston).
