SAFETY

THE FOLLOWING SYMBOL APPLIES TO ALL THE ITEMS LISTED ON THIS PAGE

A potentially hazardous situation exists which, if not avoided,

WARNING

could result in death or serious injury.

Diamond chain breakage can result in high-speed ejection of parts, which can result in death or serious personal injury to operators or bystanders. The items listed below are critical to minimizing the risk of diamond chain breakage and injury.

• DO NOT operate a diamond chain saw with a damaged, modified, broken or missing side

cover, bottom guard or guard flap. The side cover, bottom guard and guard flap provide protection against contact with moving parts, ejected debris, broken diamond chain, thrown water and concrete slurry.

• DO NOT operate saw with loose, missing, damaged or improperly repaired parts.

• DO NOT exceed the hydraulic flow for your saw model: 8 gpm (30 lpm) or 12 gpm (45 lpm)

at 2,500 psi (172.5 bar) hydraulic pressure.

• DO NOT run the saw backwards. The chain should travel away from the operator on the

top of the bar and return on the bottom of the bar.

• DO NOT insert the saw into a slot narrower than the chain segments. Rapid pushback

might occur. Reference: Most diamond segments are .225 (5.72 mm) wide.

• DO NOT use the 890 Series side cover as a replacement cover for another saw.

• DO NOT use damaged, modified or improperly repaired chain.

• DO NOT run the saw upside-down. Concrete debris can fly back into the operator’s face.

• DO NOT use your hands to search for hydraulic leaks. Hydraulic fluid escaping under

pressure can penetrate skin. If any hydraulic fluid is injected into skin seek medical attention immediately.

®

• Only use PowerGrit

Utility Saw Chain when cutting ductile iron pipe or like materials with the saw. Using chain platforms not specifically designed for this type of material may cause segment loss or diamond chain breakage.

SET-UP

890 SERIES OPERATOR’S MANUAL

STEP 8

Tension the chain. Do not over tension the diamond chain. Loss of power will result.

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, a lot of the saw's power goes into turning the chain rather than into the cut. In extreme over-tightened cases, the saw may not be able to turn the chain at all. In addition, damage can occur to the bar nose and premature stretch may occur.

CHAIN TOO TIGHT

CHAIN TOO LOOSE

If the chain is too loose, it could come off the bar, or it will allow the drive sprocket to spin without turning the chain, which can damage drive links.

When a chain stretches to a point where the drive links are hanging approximately 1/2 in (12 mm) to 3/4 in (18 mm) below the bar, it is time to tension the chain.

CORRECT CHAIN TENSION

STEP 9

Lift up on the nose of the bar and firmly tighten the side cover nuts. To prevent chain tensioner breakage, be sure the side cover nuts are tightened to approximately 20 ft-lbs (27 Nm).

890 SERIES OPERATOR’S MANUAL

OPER ATIO N

PRE-CUT CHECKLIST

• Ensure proper chain tension: The chain should be easily pulled around the guidebar by hand.

• Ensure all safety devices are properly mounted and functional and that all controls are in proper working order.

• Be sure there are no obstructions (plumbing, electrical conduit, air ducts, etc.) and no unnecessary people present

• Always wear protective clothing, including hard hat, eye protection, hearing protection, non-slip safety boots, gloves. Avoid wearing loose fitting clothing.

• Adequate water supply and pressure Minimum flow: 1 gpm (4 lpm) Minimum water pressure: 20 psi (1.5 bar)

• Proper hydraulic supply to the saw: Maximum flow: 8 gpm (30 lpm) or 12 gpm (45 lpm), depending on saw model Maximum hydraulic pressure: 2,500 psi (172.5 bar)

IMPORTANT

increase chain life is to use adequate water pressure. Insufficient water supply will result in excessive wear to the chain, which can lead to loss of strength and chain breakage, and/or damage to the guidebar nose sprocket.

PLANNING THE CUT

• Outline the cut with a permanent marker for a visual cutting guide.

• Avoid pinching the guidebar and Diamond Chain. Always cut the bottom of an opening first, then top, and then the sides. Save the easiest cut for last.

• For the straightest cuts use the “Step Cut” method. First score the entire cut line approximately 1/2 inch (12 mm) deep using the nose of the guidebar. Next, deepen the cut by about 2 inches (50

The single most important factor an operator can control to

mm). Then plunge all the way through and complete the cut using the WallWalker

®

.

• Be sure cut concrete cannot fall and injure operator or bystanders. Concrete is very heavy, one cubic foot = 12 in x 12 in x 12 in = 150 lbs (30 cm x 30 cm x 30 cm = 68 kg).

• Check for live electrical wiring near the cutting area or in the concrete to avoid electrocution.

11

OPER ATIO N

890 SERIES OPERATOR’S MANUAL

CUTTING TIPS

• To start a cut, hold trigger at full speed and slowly plunge the nose of the guidebar straight into the wall. Use the fixed WallWalker® as a pivot point and pull up on the rear handle to rotate the guidebar into the cut.

• Always operate the saw at full speed. Apply enough feed force so that the free running RPM drops 20 to 30%. If too much force is applied, the saw will lug or stall. The chain will not have enough speed to cut effectively. If too little feed force is applied, the diamonds will skid and glaze over.

• For straighter cuts use the “Step Cut” method. First score the entire cut line with the nose of the guidebar approximately 1/2 inch (12 mm) to 1 inch (25 mm) deep. Next, deepen the cut by about 2 inches (50 mm). This groove will help guide the guidebar for a straight cut. Then plunge all the way through and complete the cut using the WallWalker

®

• Use the WallWalker

to help cut more efficiently and reduce operator fatigue. The WallWalker®

®

.

is a fulcrum that converts inward force to downward force and will develop a 4-to-1 mechanical advantage. To use correctly, plunge into the wall and simply engage the point of the WallWalker® into the cut and push straight in. The WallWalker® will force the saw to feed down.

• Apply upward force on the trigger handle to keep the WallWalker® engaged properly, otherwise the WallWalker® pick will skid, which will reduce the effectiveness. As the saw begins to rotate up, feed force is developed down the line of the intended cut. Once the saw is fully rotated upwards, pull the saw out of the cut a few inches and re-engage the WallWalker® to the wall and repeat.

• When cutting rebar, slowly rock the saw so that you’re always cutting concrete as well as steel. This will help keep the diamonds exposed. Also, expect less chain life when cutting rebar.

• Expect more chain stretch and guidebar wear when making “nose buried” cuts for extended periods of time, as the chain does not have a chance to throw the slurry away from the nose of the guidebar.

• If the saw begins to cut consistently crooked, turn the guidebar over and use the other side. Dress worn rails with belt sander.

Note: The normal life of a guidebar is two to three diamond chains.

Rebar can shorten guidebar life.

• When using a new chain, you can increase the cutting speed by opening up the diamonds by making a few cuts in an abrasive material such as a cinder block.

CUTTING DUCTILE IRON PIPE WITH THE POWERGRIT® UTILITY SAW CHAIN

NEVER cut ductile iron pipe with the saw unless using PowerGrit Utility Saw Chain. The following

are safety precautions that should always be followed when using PowerGrit.

• Before cutting, make sure the pipe is in a safe condition to

be cut. Support the work piece in such a way that the cut remains open during the cutting operation and when the cut is finished. Pinching the chain during the cut could cause chain breakage and could result in death or serious injury to the

WARNING

operator.

• If using the pipe clamp accessory, the clamp must be

attached in such a way that it does not move during the cutting operation and/or when the cut is finished. Unexpected movement of the clamp could cause loss of control of the saw and could result in death or serious injury to the operator.

13

MAINTENANCE

890 SERIES OPERATOR’S MANUAL

SYSTEM CLEAN-UP

• After cutting, run the saw for at least 15 seconds with the water on to flush slurry and debris from Diamond Chain, guidebar and drive sprocket.

• Wash concrete slurry from saw assembly.

• Remove guidebar and chain. Flush out the chain tensioner and side cover with water. Lubricate tensioner with grease.

• After cleaning the saw, spray the entire saw body, chain, guidebar, and drive sprocket with lightweight oil. Using lightweight oil on the saw will minimize rust and help reduce slurry build up.

AFTER EACH USE

• Rinse the saw, guidebar and chain with water.

• Inspect and tighten all fasteners as necessary.

• Inspect, flush and grease the chain tensioner.

• Inspect drive sprocket for wear.

• Replace when the drive teeth are worn more than half way through.
