SPECIAL NOTES FOR USING RENTAL HAMMERS - CHECK THE AUTOLUBE SYSTEM EVERY SHIFT AND REFILL IF NECESSARY. - REFILL WITH EXTREME HIGH TEMPERATURE GREASE. BECAUSE OF TEMPERATURES GENERATED BY HAMMERING, GENERAL GREASE WILL NOT LAST. - CHECK TIE-BOLT NUTS AND LOCKS FOR MOVEMENT EVERY SHIFT. - DO NOT DRY FIRE THE HAMMER. MAKE SURE TOOL IS AGAINST ROCK BEFORE ENGAGING; DRY-FIRING WILL BREAK TIE-BOLTS. - DO NOT USE TOOL TO PRY. PRYING WILL BREAK THE TOOL. TOOL BITS HAVE IMPACT STRENGTH, BUT NOT A LOT OF TENSILE STRENGTH. THEY WILL BREAK IF FORCED SIDEWAYS. CUSTOMER IS RESPONSIBLE FOR TOOL BREAKAGE. - DO NOT USE THE HAMMER WITH ANY OF THE CYLINDERS, BOOM, STICK, OR BUCKET FULLY EXTENDED OR FULLY RETRACTED. USE ONLY THE MIDDLE 2/3 OF THE CYLINDER'S WORKING RANGE. IF FULLY EXTENDED OR RETRACTED, THE VIBRATION OF THE HAMMER WILL SNAP EITHER THE ROD EYE OR THE PISTON AND BREAK THE ROD. - DO NOT RUN THE HAMMER CONTINUOUSLY IN ONE PLACE FOR MORE THAN 15 SECONDS. GIVE THE HAMMER TIME TO COOL. * * * * * * * * Online Owner's Manual
