Core Product Advantages & Selling Points

High-Octane Performance & Deep Cutting Capacity

Equipped with a commercial-grade 66.7CC engine pushing 3.5kW at 8500 RPM. Paired with a 14-inch (350mm) diamond or abrasive blade, it effortlessly achieves a maximum cutting depth of 120mm, allowing you to cut through thick slabs, walls, and structural foundations rapidly.

Premium Lightweight & Mobile Ergonomics

Weighing just 9.7kg bare, it stands out as a highly maneuverable hand held concrete cutting saw. It features integrated ground mobility rollers at the base of the frame, allowing operators to roll the saw smoothly along cutting lines, significantly reducing user fatigue during long horizontal cuts.

All-Weather Easy-Start System

Forget difficult pull-starts. The XH-420 integrates an advanced recoil starter mechanism paired with a decompression valve and air purge bulb, ensuring rapid, low-effort ignition even in freezing cold weather or dusty job sites.

Advanced Safety & Debris Management

Built strictly to industrial mechanical safety specifications. Features an adjustable curved aluminum blade guard to deflect sparks and flying chunks, a secure throttle trigger lockout to prevent accidental activation, and anti-vibration rubber dampening to protect the operator’s joints.

Essential Safety & Operational Guidelines

Gas-powered power cutter is a high-speed tool. Careless or incorrect use can result in severe personal injury. Please review the following operating boundaries carefully:

  • Read the Manual: Never allow untrained individuals to operate or service this machine.

  • Medical Implant Warning: This internal combustion engine generates an electromagnetic field during operation which may interfere with active or passive medical implants (e.g., pacemakers). Consult your physician before use.

  • Ventilation: This engine produces carbon monoxide exhaust. Do not operate the saw in enclosed or poorly ventilated indoor spaces.

  • No Unapproved Modifications: Only use original XINGHU factory spare parts and approved 350mm blades. Unapproved modifications instantly void the warranty and present extreme safety risks.

Frequently Asked Questions

 

What materials can the XH-420 cut?

It is highly versatile and cuts concrete, reinforced concrete, brick, natural stone, steel pipes, rebar, asphalt, and structural wood depending on the blade type installed.

How fast can it cut through a 10cm thick concrete slab?

With a high-quality 14" diamond blade, a standard 10cm slab can be cut cleanly in roughly 10 to 30 seconds.

Will the cutting speed drop during continuous daily use?

No. The advanced forced-air cooling system ensures high heat dissipation, maintaining stable RPMs even during long shifts.

What fuel mixture does this saw require?

It requires a precise 50:1 ratio of regular gasoline to high-grade 2-stroke engine oil. Do not use straight gasoline, as this will seize the engine.

How often does the air filter and spark plug need servicing?

Clean or blow out the air filter every few uses in dusty environments. Replace the spark plug every 50 operating hours, and perform a full mechanical maintenance check every 100 hours.

How do I store the saw if I don't plan to use it for a few months?

Completely drain the 1.5L fuel tank, start the engine to run the carburetor dry, clean off all concrete slurry residue, and store the unit in a dry, cool environment out of reach of children.
