12. PILE DRIVING DO’S AND DON’TS
12.1 Do keep hammer and pile in alignment. Mis-
alignment causes excessive wear and tear on
the hammer and can cause pile damage.
12.2 Do not allow the piston to hit the catch
groove. Regulate pump down in time.
12.3 Do not exceed the maximum permissible bat-
ter as given in the specifications.
12.4 Do not attempt to start the hammer if the im-
pact block is hanging out. This will increase
the compression and most certainly damage
the catch groove and catch ring, and could
fire the piston clear out of the machine.
12.5 Do set the machine gently on a pile or on the
ground. Do not drop it on the pile. A warmed
up machine can fire if it is dropped on pile.
12.6 Do not tie the trip rope down. Keep the rope
clear at all times.
12.7 Do not operate the hammer in excess of 240
blows per foot = 20 blows per inch = 1/2" per
10 blows (8 blows per centimeter).
12.8 Do not operate the hammer with worn or bent
side guides and gibs.
12.9 If the driving is soft, use a few cold blows to
get to sufficient resistance instead of trying
to fire the hammer at the first blow.

12.10 Do not use the entire hammer as a drop
hammer to seat a pile. Use a cold blow.

12.11
Use #2 diesel fuel only. Do not use kerosene
or other substitutes.
12.12 Use specified grease only:
TRC Moly-High Temp grease
Manufactured by Texas Refinery Corp.
12.13 Do not stand in a position where you could
be struck by the hammer if it should come
down the lead at any time.
12.14 During operation, keep clear of hammer at
all times.
12.15 Keep clear of high tension power lines. (See
OSHA table at the back of this manual.)
12.16 Use safety belt when climbing leads.
13. HAMMER IN TRANSIT
13.1 When transporting the hammer, make sure to
have transport screw and safety clamp in-
stalled to keep piston and impact block from
sliding out of cylinder.
13.2 Do not run chain binders over the upper cy-
linder. Use chain binders on lower cylinder
only.
13.3 Install dust cap and exhaust port covers.
