ENGLISH
The 60523 Lightweight Cooling Fans are designed to fit Klein
Tools Hard Hats (Cap-Style and Full Brim) and Safety Helmets
to primarily focus airflow in the neck area. The independent
dual-fan design provides a great combination of adjustment,
airflow, weight, and balance for all-day comfort. The fans attach
to the side accessory slots of the hard hat and flip up out of
the way when not in use. The Lightweight Cooling Fans are
powered by a separate rechargeable modular battery (Cat. No.
29025) that can also be used to charge and/or power other Klein
Tools devices, as well as charge some other portable electronic
devices. The modular battery can be swapped out with a spare
for extended runtime.

Inspect and familiarize yourself with the components
that need to be assembled onto the hard hat or safety
helmet, then follow the instructions below to install
and use the fans. DO NOT try to rework or substitute
missing or damaged components.
INSTALLATION
NOTE: It is highly recommended that a chinstrap be
used, even for hard hat models that do not include one,
especially on jobs at-height or requiring constant head
motion. The optional Klein Tools Chinstrap (Catalog no.
KHHSTRP) is available for Klein Tools hard hats that do
not include one with purchase. The chinstrap is included
with Klein Tools Safety Helmet models.
1. Install left or right fan first by inserting the Attachment
13
Bracket
into the hard hat's universal accessory slot
from the bottom until the two retention tabs clear the
slot and click into place (FIG. C). Repeat the process
for the other fan. NOTE: If installing fans onto a
Full-Brim hard hat, you may first insert the Full-Brim
Hard Hat Attachment Bracket Adapters
universal accessory slots on the hard hat, then
insert the fans into the corresponding slots on the
Attachment Bracket Adapters.
2. Attach the battery to accessory mount on the back or
front of the hard hat, as per your preference (FIG. D).
3. Attach the Integrated USB-C Power Cable
fan to the corresponding USB-C Input/Output Port
on the battery (FIG. E).
4. To prevent the cables from snagging, dress the
Integrated USB-C Power Cables
Cable Management Clips
11
, then attach the Adjustable
Cable Management Clips
12
to the brim of the hard hat
(FIG. F).
The fans are now ready to be used.
OPERATION
The power / Mode Button
7
on each fan cycles through
Low Mode, High Mode, and off:
1. Power on the fans by single-pressing the Power /
Mode Button
7
on each fan. The fans default to Low
Mode upon powering on. Single-press the Power /
Mode Button
7
on each fan to switch to High Mode.
2. Adjust the direction of the airflow by rotating the
Adjustable Vents
10
on each fan (FIG. G).

LIGHTWEIGHT FANS: Prior to cleaning, be sure fans are
disconnected from the battery. Use clean, dry, soft lint-free
cloth to wipe down. If any debris is stuck in the fan blades or
0%
vents, gently free any objects using a blunt wooden pick. DO
charge remaining
NOT use harsh cleaning chemicals, sharp metal picks, abrasive
brushes, and/or pressurized air to dislodge stuck debris from
the fan blades. The debris may become dislodged inside the
fans and permanently damage the fans and their electronics.
Wipe down the cables with soft, clean, dry cloth. Inspect for
tears, cuts, cracks, corrosion, bent connectors, discoloration
and other such damage. DO NOT attempt to repair.
BATTERY: Prior to cleaning, be sure battery is disconnected
from the fans, any power source, or other devices. Use clean,
dry, soft-lint-free cloth to wipe down. DO NOT use abrasive
cleaners or solvents. DO NOT use sharp metal objects to clean
USB ports. Reinstall all port covers on unused ports.
Recharge as needed. There are no pre-designated intervals at
which to recharge as long as you are using regularly. Avoid
discharging completely on a regular basis, as this can impact
overall life. Regularly inspect ports and charging cable for any
debris, dirt, damage, and corrosion. DO NOT attempt to repair.
Replace battery or cables as needed.

through the Fixed
components in a cool, dry place away from direct sunlight
when not in use. If storing for prolonged periods, the battery
should be periodically charged in order to maintain battery
life, once every 3 months is recommended.
NOTE: It is highly recommended to remove the fans and
battery from the hard hat or safety helmet prior to placing
in storage.
DO NOT leave inside a vehicle or other confined spaces
in temperature extremes, or in corrosive or unsanitary
environments that can lead to decrease in service life,
overheating, or fire. After taking out of storage,visually
inspect fan, battery and all accessories for any damage.
Replace any damaged parts as needed. It is recommended
to clean each component prior to use (See CLEANING
section above).
Allow all components to return to ambient conditions before
recharging battery and/or operating.
