OPERATION & MAINTENANCE

Product catalog summary

General Information
The DSH PRO 11 Deck Scaler is a tool designed for removing rust, paint, and scale from ship decks and heavy steel surfaces. It is essential to read the manual before use to avoid damage or injury. The tool should not be used in a fixture and comes with various cutter heads and a vacuum shroud for dust control.

Safety Precautions
Operators must wear PPE, including safety goggles, footwear, ear defenders, and gloves. The tool is not electrically insulated and requires daily lubrication. It generates dust and debris, necessitating a well-ventilated workspace. Avoid using in explosive environments and do not modify the tool.

Pre-Start Check
Ensure the air supply is clean and free from water, using a minimum 19mm bore airline. Operating pressure should be between 5.5 bar (80 psi) and 6.9 bar (100 psi), with a compressor supply of at least 47 lps (100 cfm).

Starting Work
Check all fittings and ensure lubrication. Maintain a stable position during operation and move the tool back and forth for effective scaling. Avoid continuous operation in one spot.

Servicing
Maintenance should be conducted by a competent person. Disconnect from the air supply before servicing and regularly check and replace worn parts like cutter heads and pistons.

Troubleshooting
Common issues include bouncing due to high air pressure, slow performance from worn cutter heads, and dragging from insufficient air supply. Solutions involve adjusting air pressure, replacing parts, and ensuring proper air supply.

Machine Storage
For short-term storage, clean the machine and apply air tool oil. For long-term storage, additional lubrication and part inspection are required.

Machinery Directive Information
The tool complies with the 2006/42/EC Machinery Directive and EN ISO 11148-4:2010 standards. Use only genuine Unitor spare parts to maintain warranty validity.

Assembly Instructions
Detailed steps are provided for assembling the scaling head, sub-frame, wheels, and handle. Ensure all parts are clean and lubricated, and use thread-locking adhesive where specified.

Technical Specifications
Key specifications include a piston diameter of 27mm, piston length of 89mm, stroke of 26.5mm, 2300 x 11 blows per minute, air pressure of 6.2 bar, air consumption of 33 lps, dimensions of 1300mm length and 1230mm height, cutting width of 252mm, weight of 37.2kg, noise level of LpA 103.1 dB(A), and vibration at the handle bar of a=5.8 m/s².

Parts List
Includes components such as adaptors, wheel assemblies, ball valves, armoured hose assemblies, lifting brackets, locking pins, handle grips, and more.

Risk of Hand Arm Injury
Highlights the risk of hand-arm injury due to vibration emissions, ranging between 5.8m/s² and 8.1m/s², depending on task, operator's grip, and feed force.

Standards and Measurements
Noise levels are measured according to EN ISO 15744: 1999, and vibration is measured according to EN ISO 28927 and EN ISO 20643. Vibration values have a factor of uncertainty of -0% +40%.

Product Development
Unitor follows a policy of continuous product development, reserving the right to change specifications and designs without notice.

Risk of Hand Arm Injury Because of various factors, the range of vibration emission during intended use of this tool is expected to be between 5.8m/s2 - 8.1 m/s2 for this Scaler. The vibration is dependent on the task, the operators grip, and the feed force employed etc. Noise level measured in accordance with: EN ISO 15744: 1999 Vibration measured in accordance with: EN ISO 28927 and EN ISO 20643 (K) Equals the factor of uncertainty, which allows for variations in measurement and production. Vibration data figures are tri-axial, which gives total vibration emission. *In general all vibration...
