Ingersoll Rand JH40 Jackhamer Especificaciones Del Producto página 7

Controls
• The jackhamer is controlled by moving the lever as shown in Figure 1.
Operating the Tool
1. Connect the leader hose to the air connection on the jackhamer.
2. Open the latch by pushing the lever down.
3. Insert the shank end of the drill steel in the front-head, and swing the latch up to lock the
tool in the jackhamer.
Make sure the tool is the correct size for front-head: 7/8" x 3-1/4", 7/8" x 4-1/4" or 1" x 4-1/4"
depending on the chuck. Don't use a jackhamer tool that is worn; it won't do an effective
job and will cause unnecessary wear to the jackhamer.
4. Immediately after starting the jackhamer, check for the presence of oil mist at the exhaust
port and on the drill steel shank. This is the only assurance that oil is travelling all the way
through the jackhamer. When checking the jackhamer for lubrication, always put the tool
against the work.
5. Heating is not unusual in a new jackhamer and it should be checked carefully during the
first few hours of operation. In most cases, heating will be localized around the piston stem
bearing at the front end of the cylinder. Test this area frequently with the hand. As long as
the hand can be held on the part comfortably, it is safe to continue drilling. When the heat
is great enough to cause discomfort, stop the jackhamer and let it cool. Since lack of oil can
cause excessive heating, check again to see that the steel shank is oily.
6. If exhaust freeze-up occurs, add anti-freeze lubricant directly through the air inlet
connection. Use "KILFROST" anti-freeze or equivalent.
