STIHL MS 500i Specifications

STIHL MS 500i Fuel Injection

The defining feature of the MS 500i chainsaw is its electronically controlled fuel-injection system.

Rather than using a conventional carburetor, the system electronically meters fuel based on operating conditions.

For professional operators, the design provides:

• Rapid throttle response

• Fast acceleration

• Consistent fuel delivery

• Strong response under changing cutting conditions

• No conventional carburetor adjustment

This fuel-injected system is a major reason the MS 500i is used for demanding professional cutting applications.

MS 500i Power and Weight

The STIHL MS 500i combines:

79.2cc displacement
6.7 bhp engine output
13.9 lb powerhead weight

That combination gives professional operators substantial cutting power without the weight normally associated with some large-displacement saws.

The result is a saw designed for applications where both productivity and handling matter.

MS 500i Bar Options

25" Bar

The 25-inch MS 500i provides a versatile setup for professional felling, bucking, firewood production, and general large-tree work.

It offers substantial cutting capacity while keeping the overall setup relatively manageable.

28" Bar

A 28-inch bar provides additional cutting capacity and reach for larger timber.

This is a practical option for professional operators who regularly encounter bigger material but still want a versatile everyday setup.

28" Light Bar

The 28-inch Light Bar provides the reach of a 28-inch setup while reducing guide-bar weight.

Reduced front-end weight can improve saw balance during extended cutting.

32" Light Bar

The 32-inch Light Bar is suited to larger-diameter timber and applications where additional reach is necessary.

36" Light Bar

The 36-inch Light Bar provides the longest cutting setup offered on this product listing.

It is intended for large timber and professional applications requiring maximum reach.

Choosing the Right MS 500i Bar Length

Choose the bar size based on:

• Typical tree diameter

• Type of cutting

• Required reach

• Operator experience

• Working conditions

• Desired saw balance

For many professional applications, the 25" and 28" configurations provide a useful balance of cutting capacity and handling.

The 32" and 36" Light Bar configurations are better suited to applications involving larger timber.

Always verify the correct guide bar, chain pitch, gauge, and drive-link count for the selected setup.

STIHL MS 500i Chain

The supplied OILOMATIC® chain specification for the MS 500i is:

3/8" RS3

The exact replacement chain loop depends on the guide bar installed on the saw.

Before ordering replacement chain, verify:

• Guide-bar length

• Chain pitch

• Chain gauge

• Drive-link count

• Guide-bar mount

Do not order a replacement chain based only on the MS 500i model number.

Professional MS 500i Applications

The STIHL MS 500i is designed for experienced professional users performing demanding cutting work.

Typical applications include:

• Professional logging

• Forestry

• Tree service

• Large-tree felling

• Bucking

• Land clearing

• Storm cleanup

• Large hardwood cutting

• Commercial firewood production

For occasional homeowner cutting, a smaller STIHL chainsaw may be more practical.
