• Load the heaviest end of the machine and attachment

combination first.

• Lower the attachment to the floor.

• Stop the engine.

• Engage the parking brake (if equipped).

WARRANTY
BOBCAT ATTACHMENTS

Doosan Bobcat EMEA s.r.o. (“Doosan”) warrants to its authorized dealers who in turn warrants to the customer
that the Bobcat Attachments sold by Doosan, under normal use and proper maintenance shall be free from defects
in workmanship and material for twelve (12) months after delivery to the customer. During the warranty period, the
authorized Doosan dealer shall repair or replace, at Doosan’s option, without charge for parts, labour and travel of
technicians, any part of the Doosan product which fails because of defects in material or workmanship. The
customer shall provide the authorized Doosan dealer with prompt written notice of the defect and allow
reasonable time for replacement or repair. Doosan may, at its option, request failed parts to be returned to the
factory or to any other designated location. Transportation of the Doosan product to the authorized Doosan dealer
for warranty work is not the responsibility of Doosan. Service schedules must adhere to prescribed intervals and
Bobcat genuine parts/lubricants must be used. The warranty does not apply to tyres, tracks or other accessories
not manufactured by Doosan. For coverage on engines, consult with your Bobcat Dealer. For these non-covered
items, the customer shall refer solely to the warranty, if any, of the respective manufacturers thereof, in
accordance with the respective manufacturers warranty statement. Some Doosan parts are covered pro-rata
depending on the expected life-time of the part. Coverage for batteries, air-conditioning refill, couplers and
ignition system parts (glow plugs, fuel injection pumps, injectors) is reduced as failures generally originate from
factors not under Doosan’s control such as, but not limited to, prolonged storage, abuse or fuel quality. Reduced
coverage is, depending on the component, limited from 50 to 500 operating hours. The warranty does not cover: (i)
Oils and lubricants, coolant fluids, filter elements, brake linings, tune-up parts, bulbs, fuses, alternator fan belts,
drive belts, pins, bushings and other high-wear items. (ii) Damages resulting from abuse, accidents, alterations,
use of the product with any bucket or attachment not approved by Doosan, air flow obstructions, or failure to
maintain or use the Doosan product according to the instructions applicable to it. (iii) Ground engaging parts such
as bucket teeth and cutting edges. (iv) Fuel or hydraulic system cleaning, engine tune-up, brake inspection or
adjustment. (v) Adjustments or slight defects which generally do not affect the stability or reliability of the
machine.
