Safety
Safety is designed into every detail of the KX91-3. An Engine Start Lockout System prevents the engine from starting when the safety levers are lowered. A Safety Lever Lockout System helps prevent unexpected excavator and attachment movement when entering or exiting the machine. An Auto House Parking Brake automatically locks the house in the position it was in when the engine was shut off, eliminating the need for a swing lock pin. It also makes the excavator more compact during transport and more secure when parked on an incline.
Maintenance Simple maintenance keeps the KX91-3 working longer.
Accumulator

The accumulator makes replacing attachments safer and more efficient. Turning the key to the "on" position clears residual pressure in the auxiliary hyd. hose, preventing oil from spewing out when replacing attachments. If the engine is accidentally shut off while the front attachment is raised, turning the key to the "on" position allows you to safely lower it.
Engine Hood

No key is required for daily or periodic maintenance. With the push of a button, the engine hood opens wide to allow quick and easy access to the engine, fuel tank, coolant reservoir, and hydraulic components. Anti-vandalism locking is also standard feature.

Two-piece Hose Design
The two-piece hose connections for the dozer and boom cylinder hoses simplify hose replacement and reduce downtime.

Engine Room Fuel Filter

Improved and now easier to access, the independent water separator and fuel filter provide enhanced fuel and water filtration, increased durability and greater overall excavator performance.

Enlarged Fuel Tank
he fuel tank is now larger by 1.3 gal., letting you work 10% longer. The larger tank means less worry about running out of fuel on jobs what demand long hours.

 
Automatic Swing Parking Brake
The swivel negative brake automatically locks the house in place when the engine is off, without setting lock pins. Now you can easily lock the house in any position for more compact transportation.
Protected Cylinder Hoses
The bucket cylinder hoses are located inside the arm. And the boom cylinder hoses are routed under the boom bottom.
Centralized Swivel Bearing Lubrication
Grease ports for the swivel bearing, gear teeth, and swing cylinder pin are conveniently grouped on the front of the house.
