Page 4: Safety
1 SAFETY 1.1 INTRODUCTION Your Reimann & Georger Corporation C120 HydraCutter has been engineered to provide sawing performance, long term economics and safety advantages that no other type can match. However, even a well-designed and well-built saw 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 saw to provide maximum safety for all operating personnel, and to get the maximum benefit from your equipment. - Page 5 11. Always carry the saw in its de-energized state. 12. Keep the saw handles dry, clean, and free of oil or fuel. 13. Do not start cutting without first de-energizing electrical wiring near the cutting site or imbedded in the concrete. 14.

2 SPECIFICATIONS 2.1 INTRODUCTION Your Reimann & Georger Corporation C120 HydraCutter hydraulic hand-held chainsaw is a rugged versatile tool that makes clean, fast, precise, and straight cuts through concrete, reinforced concrete, masonry, stone, and other aggregates. As with most hydraulic tools, the hydraulic system requirements detailed in the following sections must be met but not exceeded to support tool performance and longevity of equipment. -
Page 7: Recommended Hydraulic Oil
Many types of compatible hydraulic oil are available through your local dealer/distributor. As an original equipment manufacturer, RGC uses a Grade ISO VG 32 hydraulic turbine oil. Hydraulic oil types are too numerous to list in this manual. If you have any question concerning the type of oil suitable for C120 operation, please consult your local supplier or Reimann &... -
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 saw 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 saw 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/drive link tang arrow pointing towards bar nose on top side of bar. 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. -
Page 11: Breaking In A New Chain
For long vertical or horizontal cuts, the cutting line can be first scored with a groove using the nose of the bar. The groove will help guide the bar for a straight cut. 3.4 BREAKING IN A NEW CHAIN Before using a new chain, the cutting segments must be dressed by cutting in an abrasive material such as cinder blocks or bricks. - Page 12 WARNING: NEVER DISCONNECT ANY HYDRAULICALLY OPERATED PART OF THE SAW OR REMOVE HYDRAULIC COMPONENTS, LINES, OR FITTINGS WHILE THE POWER SOURCE IS RUNNING OR WHENEVER THE HYDRAULIC FLUID IS HOT. Allow the water to drain out of the saw by pointing the nose down and triggering the valve on. If available, blow the water out of the saw with compressed air.

Page 13: Inspection And Maintenance
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 saw’s life. Refer to the respective manual for maintenance information on the hydraulic power source. - Page 14 Check the clearance between the nose of the bar side-plates and the chain chassis; when new, there is 1/32” clearance. The bar must be replaced before the chain chassis begins to ride directly on the nose of the bar side-plates. Refer to Figure 4-2. Figure 4-2 Nose Sprocket Clearance The bottom rail wears at a much faster rate than the top rail because of the downward motion during cutting.

Page 15: Drive Sprocket Inspection And Installation
4.3 DRIVE SPROCKET INSPECTION AND INSTALLATION Refer to Figure 4-3. The sprocket assembly consists of external retaining ring (#28) and drive sprocket (#27). Proceed as follows: Check the wear marks on the driving face. Replace the drive sprocket before the wear marks are deeper than 1/32” as shown in Figure 4-4. -
Page 16: Chain Inspection And Maintenance
4.4 CHAIN INSPECTION AND MAINTENANCE Inspect the chain before mounting and before each use. Ensure there are no missing segments or bumpers. There must be 49 segments with a bumper link between each segment. Ensure there are no signs of cracking, overheating, or other damage. Check the wear of the chain chassis, typically referred to as “chain stretch”, by tensioning the chain as described in Section 4.5. -

Page 20: 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. -
Page 21: Operational Factors Affecting Chain Life
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 22: 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. -
