AllSaw

The Allsaw can cut:

• Mortar
• Soft to medium hard brick
• Aerated concrete block
• Limestone
• Fiberboard
• Weatherboard
• Composite

There is no exact answer as each project and end-user is different. When installed and used correctly, the Allsaw blades should meet expectations, but it's essential to note that they are consumables and not covered under warranty.

The AS175 is supplied ready to use. However in some cases the blades may need to be changed to suit the application. Before changing blades, the guard around the blade mounts must be levered gently out of its groove at the front of the tool and swung away to give access to the cap screws. Then use the “Ian key” supplied to loosen and remove the cap screws securing the blades, and remove the blades.

Select the correct blades for the cutting task and mount each with their cap screws. Verify that the surfaces of the blade mounts, conrod thread and screws are clean and free of grit or lubricant before fitting. Ensure the guard can be closed before fixing the blades to the conrod.

NOTE: Always use matched pairs of blades. Never mix used blades with new blades. Use only the bolts supplied with the tool.

IMPORTANT: Use the “Ian key”, to tighten the blade mounting screws until the torque indicator coil deflects sufficiently so that the sides meet. The “Ian Key” will tighten the bolts to the required 18Nm.

CAUTION: Do not operate the tool if the blades are loose. Operation with loose blades will severely damage the blade mount & bolts requiring repair.

NOTE: Blades are a wearing part. In normal operation, blade life may vary with the hardness of materials cut. Check that the teeth of the blades are lightly contacting, or within approximately 1 mm of contacting each other.

If the gap between the blades is too large, remove and gently bend inward to adjust the gap. Ensure that both blades are aligned vertically to the tool.

CAUTION: If the blades rub against each other anywhere other than within 25mm/1” of the cutting edge, or contact force is high, it is possible to overload the tool and cause premature belt wear.

Swing the guard into its groove at the front of the tool and snap it into place. 

• Make sure to tighten the bolts to the required 18Nm using the Ian key supplied. 
• Check that no dirt or lubricant is between the blade and the conrod.
• Check the blade mount holes. If these holes become elongated (evidenced by damage inside the hole from the screw thread) the blades should be replaced. The Blades rely on close tolerances for good operation, any form of deformation of these mounting holes, combined with the hammering motion of the saw, will induce movement which will work to loosen the blade mounting screws.

Remove blade/s and bend slightly to correct.

Note: If the blades rub against each other anywhere other than within 25mm / 1″  of the cutting edge, or contact force is high, it is possible to overload the tool and cause premature belt wear.

• Check that all cooling vents are not obstructed by the operator's hand, debris in vents, or other. Clean as required.
• Check the blade condition. Excessively worn blades can cause overheating. Replace as required.
• Check the clearance between the blades. (Please see the changing blade section)
• Check that belt tension is not excessive. (Please see changing belt section)

• Check that bearings have not failed by removing plastic side cover and belt and rotating both pulleys independently checking for roughness. The power pulley should rotate easily and smoothly. If a bearing has failed contact Arbortech Customer Support.
• Check blade tension, if loose -tighten blade mounting bolts.
• Possible blade failure – replace blade set.
• Leaf spring failure – contact Arbortech Customer Support.
• Gearbox failure – contact Arbortech Customer Support.
• Top handle rubber mounts damaged or worn – replace.

• Loose belt – re-tension belt (See loose belt section)
• Worn belt – replace belt (See worn belt section)
• Worn pulleys – contact Arbortech Customer Support 
• Attempting to cut material which is too hard

• Teeth worn, chipped or lost. Sharpen or replace blade.
  Check to see if the belt is slipping and belt tension (See belt tension section)

This is normal in approximately the first hour that the new tool is operated or if new bearings have been installed. Leakage should reduce and stop thereafter.

Worn or damaged rubber bushes – replace.

• Check to make sure brushes are not damaged or excessively worn. Replace as needed.
• Check power cord for damage – contact Arbortech Customer Support.
• If the tool is still not operating - contact Arbortech Customer Support.

With use, the blades will become dull and the cutting performance will decrease. This can be largely restored by re-sharpening the teeth with a fine grit diamond disc.

• Using an incorrect cutting action can cause the blades to overheat, melting the solder and releasing the teeth. Please see the cutting technique section.
• Material is too hard.
• Care not taken in setting tools down on teeth on hard surfaces or loose in the tool box.
• Striking metal inside material

• Threads on bolts stripped – replace bolts not tightening.
• Threads on tool stripped – contact Arbortech Customer Support.

We recommend using heavy duty (12 or 14 gauge) extension cord up to 50 Feet.

No, because the farther the cutting edge is from the motor, the less power is transferred to the cutting surface.

Repair options vary depending on the issue. Some repars can be done locally, like brushes or belt replacement. Other repairs, like sheared-off blade bolts, require te expertise of Arbortech's US Repair Center.

Consider resharpening the Allsaw blades with a standard diamond file. Also, pairing the Allsaw with our Mini Grinder Trade. Scoring the masonry joint will help alleviate the pressure on it and can optimize the Allsaw's capabilities.
