expressly limited to repairing or replacing, at J&M's option, any parts which appear to J&M
upon inspection to have been defective in material or workmanship. Such parts shall be
provided at no cost to the user at the business establishment of J&M or at the J&M distributor
of the product during regular working hours.
This warranty shall not apply to component parts or accessories of products not manufactured
by J&M and which carry the warranty of the manufacturer thereof or to normal maintenance
parts (such as filters).
Replacement or repair parts installed in the product covered by this warranty are warranted
only for the remainder of the warranty as if such parts were original components of said
product.
J&M's obligation under this warranty shall not include any transportation charges, costs of
installation, duty, taxes or any other charges whatsoever, or any liability for direct, indirect,
incidental, or consequential damage or delay.
If requested by J&M, products or parts for which a warranty claim is made are to be returned
transportation prepaid to J&M.
Any improper use, including operation after discovery of defective or worn parts, operation
beyond rated capacity, substitution of parts not approved by J&M or any alteration or repair by
others in such manner as is J&M's judgment affects the product materially and adversely shall
void the warranty.
For impact pile hammers, driving in excess of 10 blows per inch (set of 0.1 inch per blow) is
considered practical refusal. Driving in excess of 10 blows per inch for more than 6 inches of
driving or driving in excess of 20 blows per inch at all is considered improper use and will void
the hammer warranty.

refusal. Driving when penetration is less than 1" per minute for more then 5 minutes of driving
or driving at all when penetration is less than 1" per minute and amplitude is greater than
1" (vibrator and pile are bouncing) is considered improper use and will void the vibrator
warranty.

merchantability or fitness for any particular purpose.
No employee or representative is authorized to change this warranty unless such change is
made in writing and signed by an officer of J&M.
