17. When operating in an enclosed area, pipe exhaust fumes outside. Continued
breathing of exhaust fumes may be fatal.
18. When servicing batteries, do not smoke or use open flames in the vicinity. Batteries
generate explosive gas during charging. There must be proper ventilation when
charging batteries.
19. When filling fuel tank, do not smoke or use open flame in the vicinity.
20. If abnormal equipment operation is observed, discontinue use immediately and
correct the problem. Do not leave the equipment control pendant (radio control)
unattended.
21. Store oily rags in approved containers, and away from engine exhaust system.
22. Make sure that the hammer is OFF before starting the power unit engine.
23. Do not adjust, or set, hydraulic pressures higher or lower than those specified in the
manual.
24. Never operate this equipment with hydraulic hoses that are damaged or “kinked”.
Replace damaged hoses immediately.

26. Never attempt to connect quick disconnects when the power unit is running.
27. Do not pull on, or attempt to move equipment, with hydraulic hoses.
28. Do not attempt to locate hydraulic leaks with your hands. High pressure hydraulic
leaks can penetrate the skin, causing severe damage, blood poisoning and

35. When moving or transporting this equipment, be sure that quick disconnect dust
caps are tight, and that cap safety cables are in place. Be sure that all equipment
parts are tight, or properly secured, before shipment. Unsecured parts may vibrate
loose and fall, during transport, causing injury or property damage.
