Description
Trim medium tree limbs along park trails and estate grounds with lightweight, fuel-efficient gas power. The Stihl HT105-Z 12 Inch Bar gas-powered telescoping pole pruner reaches high branches from solid ground. This commercial pruner grooms trees across golf courses, municipal park trails, and landscape routes. It cannot tackle thick timber trunks exceeding ten inches.
A fuel-efficient 31.4cc 4-MIX engine links to a rigid square-profile telescoping drive shaft inside an extruded aluminum pole. The engine delivers rapid acceleration and low emissions while running on standard two-stroke gas mix. A compact cast magnesium cutting head houses a 12-inch Rollomatic E Mini guide bar and 3/8-inch Picco Micro chain. A cast metal branch hook helps pull severed limbs down through tree branches.

Arborist Operation Safety Boundary Guidelines
Mix two-stroke oil at fifty-to-one with fresh gasoline, prime the bulb, pull the starter cord, adjust the telescoping nut, and cut with the base of the bar. Make undercut relief notches on heavy limbs first. Never operate this metal-shaft pole pruner near energized utility power lines.
- Engine valve clearances require checking and adjustment to 0.004 inches annually
- Spark arrestor screen inside the muffler requires wire-brush cleaning every fifty hours
