SET-UP 701-A SERIES OPERATOR’S MANUAL CAUTION CORRECT CHAIN TENSION All chains have a tendency to stretch when used. Diamond chains stretch more than wood cutting chains because of the abrasive materials they are cutting. If the chain is too tight, more power goes into turning the chain rather CORRECT CHAIN TENSION than into the cut.
OPERATION 701-A SERIES OPERATOR’S MANUAL PRE-CUT CHECKLIST CAUTION To maximize the life of the cutting system, ensure that proper chain tension is maintained. If tension is too tight, it will lead to excessive chain stretch, and a lot of the power cutters power will be used to overcome friction.

OPERATION 701-A SERIES OPERATOR’S MANUAL PRE-CUT CHECKLIST, CONT. • Adequate Water Supply and Pressure: Minimum Flow: 1 gpm (4 lpm) Minimum Water Pressure: 20 psi (1.4 bar) Checking for water pressure without a pressure gauge: With the compressor off, attach water hose to the power cutter water connection. Pull the chain off to one side of the bar and turn on the water valve.

OPERATION 701-A SERIES OPERATOR’S MANUAL WARNING If cutting pipe with PowerGrit® be sure the cut line stays open by providing proper pipe support. Also check for neighboring utilities or obstructions. Concrete is very heavy, 1 cubic foot (30 cubic cm) weighs 150 lbs (68 kg). Be sure to cut so that concrete cannot fall and injure operator or bystanders.

TROUBLESHOOTING 701-A SERIES OPERATOR’S MANUAL • SLOW CHAIN SPEED - Be sure the compressor is providing the correct air pressure at the power cutter (90 psi = 6 bar) and cubic feet per minute (124 cfm = 3.5 m /min). Chain is installed too tight. Refer to tension on page 11.
MAINTENANCE 701-A SERIES OPERATOR’S MANUAL DRIVE SPROCKET INSTALLATION STEP 1 • Remove snap ring • Remove sprocket • Install sprocket in reverse order ensuring counter bore is facing out. • Install snap ring STEP 2 • Ensure snap ring is fully seated in snap ring groove.

MAINTENANCE 701-A SERIES OPERATOR’S MANUAL AIR MOTOR MAINTENANCE Service life and performance of the chain power cutter are determined by: 1. Degree of air purity 2. Lubrication 3. Maintenance Prior to operating the power cutter be sure to: 1. Blow the air hose clear prior to connecting it to the power cutter. Install dirt and water separators upstream of the power cutter 6 - 12 ft (2 - 4 m).
REFERENCE 701-A SERIES OPERATOR’S MANUAL APPROXIMATE CUTTING RATES Material Cutting Rate Concrete – 6 in (15 cm) 5 lineal in/min (12 cm/min) Red Brick – 6 in (15 cm) 10 lineal in/min (25 cm/min) Rebar – #4 (12 mm) 10–20 seconds through each piece *Rebar must be encased in concrete, never cut bare rebar with ICS Diamond Chain.
