General Maintenance Information
• Observe the safety regulations!
• Only qualified, authorized persons may carry out repairs.
• In the event of faults, refer to the Operation and
Maintenance instructions for correct operation
and maintenance.
• If the fault cannot be located, refer repairs to an authorized
D
WALT service center.
e
• Always first check items that are easily accessible (fuses,
LEDs, etc.).
• Avoid contact with rotating parts.
• Only carry out maintenance with the motor switched off.
• Before carrying out maintenance work, remove the battery.
• Clean the motor and machine prior to carrying out
maintenance work.
• Park the machine on a level surface and secure to prevent
rolling and slipping.
• Ensure that lubricants and replacement parts are disposed
of in a safe and environmentally acceptable manner.
• Avoid short‑circuits on current‑carrying cables.
• After washing, blow components dry with compressed air
to prevent creepage currents.
• Rammers must be tested for safety depending on the
operating conditions required, at least once a year by an
authorized D
WALT service center.

Screw Connections
With vibrating devices, it is important to intermittently check
the screw connections for tightness. Pay attention to the
tightening torque.
Checking the Rubber Buffers (Fig. N)
Check the rubber buffers
as well as for secure fit. If they are damaged, replace
them immediately.
Checking the Bellows (Fig. O)
• Check the bellows
defective bellows immediately.
• Check mounting clips

Checking the Oil Level (Fig. Q)
1. Set the rammer aside horizontally.
iMPORTAnT: Let the rammer stand for a little while so that
the oil can run back into the housing.
2. Clean the oil sight glass
3. Check the oil level.
4. The oil must be at least up to the upper edge of the sight
glass. If the oil level is low, take the rammer to an authorized
D
WALT service center to have the oil topped off or replaced.

If the machine is to be shut down for an extended time
61
(longer than six weeks), it should be placed stably on a pallet
106
on a firm, even surface. If the machine is stored standing up,
it should secured from tipping over.

• The storage area should be dry and protected.
269
• The ambient temperature should be between 32 °F (0 °C)
368
and 113 °F (45 °C).
523
• Before storing the machine:
‑ Clean it thoroughly.
715
‑ Check for leaks and damage, and fix any problems.
899
‑ Cover it with a protective tarpaulin.

Before returning the machine to service, check the
machine for:
• leaks,
• defective or leaky hydraulic hoses,
• any other damage.
Check all screw joints and tighten them.
Cleaning
WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk of eye
injury, always wear ANSI Z87.1 approved eye protection when
performing this procedure.
