Description
Clear tree limbs around energized utility corridors without risking electrical arc-flash injuries. The Husqvarna 525DEPS MADSAW Pole Saw dielectric gas-powered pruner insulates utility arborists working near high-voltage lines. This commercial machine cuts branches along distribution line rights-of-way and storm damage zones. It cannot serve as an insulated hot stick for electrical line manipulation.
A tested non-conductive dielectric fiberglass shaft insulates the operator, meeting OSHA 1910.269 and ASTM F711 safety certifications. The commercial 25.4cc X-Torq gas engine links to an insulated internal drive system, generating 1.36 HP with low exhaust emissions. A heavy cast magnesium cutting head houses a 10-inch commercial guide bar and narrow-kerf cutting chain driven by an automatic oil pump. The modular disconnect allows compact truck storage.
Dielectric Utility Gas Pruner Specs
Utility line-clearance contractors require certified non-conductive gas pole pruners to clear thick branches near live wires. This machine delivers high cutting torque while protecting tree crews.
- 25.4cc X-Torq commercial gas engine generates 1.36 HP for high branch-cutting torque
- Non-conductive fiberglass shaft insulates operators, meeting OSHA 1910.269 and ASTM F711
- 10-inch commercial guide bar cuts dense hardwood branches up to eight inches thick
- Modular shaft disconnect separates into sections for secure utility truck box storage
- Automatic chain oiling mechanism keeps bar grooves lubricated during vertical cutting passes
- Heavy-duty pleated air filter blocks sawdust ingress in dry utility right-of-way cuts
- Inertia-balanced rear engine position counterbalances cutting head weight during high reaches
Dielectric Insulation Bench Telemetry Tests
High-voltage dielectric testing subjects the dry fiberglass pole to 100 kV AC potential across a twelve-inch section for five minutes, showing leakage currents below 50 microamperes. The 25.4cc engine turns at 8500 RPM under cutting load, driving the chain at 4100 FPM. Fuel consumption measures 0.22 GPH at wide-open throttle, delivering forty minutes of cutting per tank. Acoustic sound levels measure 96 dBA at the operator ear level.
Utility Line Clearance Boundary Limits
Inspect the fiberglass shaft for cracks, start the engine on level ground, attach safety harnesses, and cut with the base of the bar. Keep the tool clean and free of moisture. Do not operate this unit if the fiberglass pole shows surface gouges, grease contamination, or rain moisture films.
- Dielectric fiberglass shafts demand alcohol wipe cleanouts and silicone wax before every shift
- Air filter pleated elements require inspection and tapping clean after every twenty hours
- Guide bar rails require deburring with a flat file every twenty operating hours
Commercial Utility Tool Crate Manifest
Husqvarna backs this 525DEPS MADSAW with a 2-Year commercial limited warranty. The shipment package includes the dielectric gas pole saw unit, 10-inch guide bar, cutting chain, bar scabbard, scrench tool, and dielectric safety documentation manual.
