Page 4: Safety
1 SAFETY 1.1 INTRODUCTION Your Reimann & Georger Corporation Mini HydraCutter has been engineered to provide cutting performance, long term economics and safety advantages that no other type can match. However, even a well-designed and well-built HydraCutter can malfunction or become hazardous in the hands of an inexperienced and/or untrained user. Therefore, read this manual and related equipment manuals thoroughly before operating your HydraCutter to provide maximum safety for all operating personnel, and to get the maximum benefit from your equipment. - Page 5 10. Always carry the HydraCutter in its de-energized state. 11. Keep the HydraCutter handles dry, clean, and free of oil or fuel. 12. Do not start cutting without first de-energizing electrical wiring near the cutting site or imbedded in the concrete. 13.

Hydraulic oil types are too numerous to list in this manual. If you have any question concerning the type of oil suitable for MINISAW operation, please consult your local supplier or Reimann & Georger Corporation for details. 2.4 NAMEPLATE AND SERIAL NUMBER TAG It is important to identify the MiniSaw completely and accurately whenever ordering spare parts or requesting assistance in service. -
Page 8: Operation
3 OPERATION 3.1 CHAIN SELECTION Correct chain type selection is critical in maximizing chain life and cutting performance. Refer to the table below as a guide in the chain selection. However, no direct rule determines which chain type is optimum because many material factors also influence selection. -
Page 9: Checking Water Supply
The water pressure at the HydraCutter must be between 50–160 psi (3–9.6 bar) with a flow rate of 2.5 gpm (9 lpm). For best performance, use an RGC in-line water pump. Permanent chain, bar, and drive and nose sprocket damage will occur if the HydraCutter is run without water, or with a water volume or pressure that is too low. -
Page 10: Planning The Cut
Figure 3-1. Proper Chain Mounting The chain MUST be installed with the bumper link leading the diamond segment. See Figure 3-1. Backward (reverse) chain installation can cause excessive vibration, rough cutting, reduced chain life, and chain breakage. Check for proper chain tension as described in Chapter 4. Check that the chain guard is in the mounting grooves and that the socket head screw is tight. -
Page 11: Cutting Procedure
3.5 CUTTING PROCEDURE WARNING: THE CHAIN GUARD MUST BE IN PLACE BEFORE STARTUP AND DURING SAW OPERATION. FAILURE TO DO THIS CAN CAUSE SERIOUS PERSONAL INJURY. Review all safety procedures in Chapter 1 of this manual and in the manual supplied with your hydraulic power unit. Grasp the auxiliary handle with your left hand. - Page 12 Secure the HydraCutter and hydraulic power source to prevent unauthorized use. Store the HydraCutter away from excessive heat or moisture. Store in a clean, dry area away from exposure to high humidity, water, other liquids, or freezing temperatures. Avoid temperatures low enough to cause condensation on the chain when moving it from storage to a higher temperature.

4 INSPECTION AND MAINTENANCE 4.1 GENERAL MAINTENANCE RULES Hydraulic fluid can become contaminated after extended periods of use which can cause restrictions in the system. Check to see that the fluid is clean, and change at recommended intervals to extend MiniSaw’s life. Refer to the respective manual for maintenance information on the hydraulic power source. -
Page 14: Nose Sprocket Replacement
CAUTION: NEVER RUN THE SAW WITH PLUGGED WATER PORTS. THIS CAN CAUSE OVERHEATING AND RESULTING EQUIPMENT DAMAGE. 10. Ensure the bar and nose sprocket have a light coat of oil to prevent rusting. Figure 4-1 Dressed Bar Rail 4.3 NOSE SPROCKET REPLACEMENT The nose sprocket will wear more quickly than the bar rails under normal working conditions. -

Page 16: Chain Inspection And Maintenance
After each use clean the slurry and debris off the chain; then apply a light coating of oil to prevent rusting. A broken chain that is not worn-out can be repaired. There is a complete line of chain repair accessories available from RGC. - Page 17 Install the chain cover (#19) and install the two flanged hex nuts (#29) but do not tighten at this time. Tighten the bar adjustment screw (#45) clockwise until chain is snug to the bar but still able to rotate around the bar. Chain tension needs to be readjusted before the drive tangs can come completely out of the groove.

Page 21: Factors Affecting Chain Life
6 FACTORS AFFECTING CHAIN LIFE Optimum performance from your chain saw will depend largely on selecting the proper chain for the application. If the cutting medium is too soft for the chain rating used, you may get fast chain wear. If the cutting medium is too hard for the chain rating used, you will get segment glazing and/or very poor cutting performance. -

Heavy • 5/8” (16 mm) diameter or larger with any center distance • 1/2” (13 mm) diameter or larger with less than 4” (100 mm) center distance • Pre-stressed cable/wire Light • 1/2” (13 mm) diameter with greater than 4” (100 mm) center distance •... -
Page 23: Chain End-Of-Life Modes
Mode of Cutting Plunge vs. Slab—Plunge cutting increases diamond segment wear because both impact and loading increase. Depending on the ratio of plunges and the cutting depth, chain life can be reduced. Buried nose vs. Through cut—When cutting with the bar nose buried in the cut, the slurry increases the wear on both the chain and segment. -
