● Easy Access to Engine Oil
Filter and Fuel Drain Valve
Engine oil filter and fuel drain
valve are remotely mounted to
improve accessibility.
Reducing Maintenance Costs
● Hydraulic Oil and Filter/Engine Oil and Filter
Replacement Interval Extended
The new high performance filters are used in hydraulic circuit
and engine. Hydraulic oil filter, engine oil, and engine oil
filter element replacement intervals are significantly extended
to reduce maintenance costs.

Self-Diagnostic Monitor
The PC220-7 features the most advanced diagnostics
system in the industry. The Komatsu exclusive system
identifies maintenance items, reduces diagnostic times,
indicates oil and filter replacement hours and displays error
codes.
Continuous Machine Monitoring System
When turning starting switch ON, Check-before-starting
item and caution items appear on the liquid crystal panel.
If abnormalities are found, a warning lamp blinks and
a warning buzzer sounds. The continuous machine condition
checks help prevent the development of serious problems
and allows the operator to concentrate on the controls.
Abnormalities on Electronic System Display
with Code
When an error occurs during operation, a user code
is displayed. When an important user code is displayed,
a caution lamp blinks and a warning buzzer sounds
to prevent the development of serious problems.
Oil Maintenance Function
When machine exceeds oil or filter replacement time,
oil maintenance monitor lights to inform operator.

Easy Maintenance
Komatsu designed the PC220-7 to have easy service access.
We know by doing this, routine maintenance and servicing are
less likely to be skipped, which can mean a reduction in costly
downtime later on. Here are some of the many service
features found on the PC220-7.
● Easy Radiator Cleaning
Clearance between radiator
and oil cooler is increased
to facilitate radiator core
cleaning with an air nozzle.
● Water Separator is
standard equipment,
removing water mixed in
fuel and preventing fuel
system damage.
● Self-diagnostic Monitor
allows display of vital self-
diagnosis, as well as displaying up to 39 different faults.

● Fuel Tank Capacity Increased
Fuel tank capacity is increased from 340 ltr 89.8 U.S. gal
to 400 ltr 105.7 U.S. gal to extend operating hours before
refueling. Fuel tank is treated for rust prevention and
improved corrosion resistance.

All Work Equipment Lubrication Intervals Are
500 Hours with optional BMRC Bushings
(except bucket pin bushings)
Newly developed BMRC bushings are used on the work
equipment. All bushing lubrication intervals of work equipment
are extended from 100 hours to 500 hours (except bucket
pin bushings), reducing maintenance costs.
BMRC (Beta Matrix Reinforced Copper Alloy)
A bushing made by combining a
sintered copper layer
impregnated with oil for better
fitting and a backing metal. It is
used for severe application parts
which receive low rocking
stresses and high loads to
prevent creaking and scuffing
because of its excellent sliding
characteristics.

operation hydraulic flow
A newly developed Multi-Function Color Monitor has multiple
functions, such as Working mode selection, hydraulic pump
oil flow adjustment for matching to attachment, and
maintenance interval notice, etc.
Working Mode Selection
The Multi-Function Color Monitor has Lifting mode in
addition to the standard three-mode selection
(A, E, and B modes).
Hydraulic Pump Oil Flow Adjustment System
When installing attachments (breaker, crusher, etc.) and
B, A, or E mode is selected, it is possible to adjust engine and
hydraulic pump discharge flow to match attachment
characteristics. Selection is possible throughout the LCD
(Liquid Crystal Display). This system also allows throttling
of the attachment side discharge flow to provide smooth
work equipment movement and compound operation
with work equipment and attachment.

Automatic Three-Travel Speed
Travel speed is automatically shifted from high to low
speed according to the pressure of the travel. This optional
system is available as part of the Multi-Function Color
Monitor.
Lifting Mode
When the Lifting mode is selected,
lifting capacity is increased by
7% by raising hydraulic pressure.
