After each forty-eight hours of operation, remove the Hammer Case and check the grease
content. If the parts (especially the jaws of both the Hammer and Anvil) are not well coated with
Ingersoll Rand No.100 Grease, shorten the interval between each greasing. If the Hammer Case
is grease loaded, lengthen the interval. Before replacing the Hammer Case, be sure that the
jaws on the Hammer and Anvil and all bearing surfaces are coated with grease. Also, insert one
teaspoonful (3 cc) of grease into each hole in the side of the Hammer to lubricate the Cam Balls.
Do not grease the cylindrical surface of the Hammer; this is not a bearing surface. Remove any
excess grease, especially any that may have accumulated on the hammer case wall.
Oiler Adjustment
Adjustment is made at the factory and should not be changed unless lubricating difficulties are
experienced. If adjustment becomes necessary, remove the Hammer Case Bolts and Backhead
Cap Screws and holding the Motor Housing onto the Gear Case and remove the Housing. A small
Adjusting Hole Plug is located in the Housing's front face. Remove this Plug, as well as a similar
Plug on the side of the Housing. The Adjusting Screws are located beneath the Plugs. Turn the
Oiler Adjusting Screws with a small screwdriver. Turning the Screws in reduces the oil flow;
backing the Screws out increases the oil flow. Two Oiler Felts are located under each Screw.
After long usage, these Felts may become clogged, preventing the passage of oil. If this happens,
remove the Plugs and Screws and replace the Felts.
Governor Adjustment
The drawing TPD497 on page 2, illustrates the sensitive weight-type Governor which controls
the speed of the Multi-Vane motor. It is adjusted at the factory to produce a socket speed of
approximately 355 rpm. It is seldom necessary to change this adjustment. However, if the
free speed of the square driver is checked with a tachometer and is not within 5 rpm of the
recommended speed of 355 rpm, steps should be taken to correct it. Screwing the adjusting nut
farther onto the governor stem increases the speed; backing the nut off decreases the speed,
One-half turn of the nut will vary the socket speed about 5 rpm.
When installing a new Governor, set the Nut so that dimension "A" is 1-3/4" (44 mm). This usually
produces an allowable speed.
