Trow & Holden Pneumatic Carving Tools PDF Owners Manual

Thank you for buying a Trow & Holden Co. pneumatic stone carving hammer. As inventors of the first pneumatic carving tool in 1890, we have had many years to perfect these tools and to expand our range of sizes to suit the needs of all our customers Whether you’re working in small blocks of alabaster or large blocks of granite, if you feel the tool you have received is not a comfortable size for you, we wil1 gladly exchange it for another. You may have noticed that your Trow & Holden pneumatic toot has a number on it.

That is a distinct serial number and with it we have registered the tool in your name. Unique details of each batch of tools are kept on file, so if your tool ever needs repair, we can determine its exact specifications before beginning work. Each tool is guaranteed for life against breakage or defect. Because this tool has only one movable part, it is difficult to wear it out. We know of tools that are nearly 100 years old that are still in use. You made a great investment when you bought a Trow & Holden pneumatic tool!

BREAKING IN YOUR TOOL
We made your Trow & Holden pneumatic tool to very precise specifications. The piston fits the cylinder with a .0002” tolerance (2/10ths of 1/1000th an inch!) so that your tool will perform consistently and not wear out for a very long time For that reason, it may take 100 or more hours of use before your tool achieves its maximum power level. We believe this slight reduction in power during early use will not significantly effect the tool’s efficiency, but if it presents a problem, please call us to discuss your needs. If and when your piston ever wears 0ut enough to need replacement, you will know by the excessive air leakage around the nose end. Please send in the whole tool so we can replace the nose bushing at the same time, thereby duplicating the fit and performance of a new tool. Replacement of the piston and nose bushing due to normal wear are not covered by warranty.

SAFETY
A common-sense approach to safety should be maintained while using any Trow & Holden stoneworking tool. To protect yourself from flying stone chips, always wear safety glasses whether you are using hand or power tools. These are available from us for $10.00, or any hardware store carries them. The best type are those that completely cover your eyes. You may find that you are generating more stone dust with your pneumatic hammer. We suggest that you either install a dust collection system or wear a respirator. Because pneumatic hammers make noise, we recommend that you wear earplugs while using your tool. Wrist supports may help prevent wrist strain and shock-absorbing gloves may increase your comfort whether you are using hand or pneumatic hammers. Strain and fatigue lead to accidents, so equipment that helps prevent these two conditions will improve safety. Don’t forget that taking breaks and changing hand positions frequently while working will also help prevent fatigue.
