3 | Safety Precautions
Before Operation
Before starting for the first time: DO NOT START fan if there are any signs of shipping damage,
particularly to blade, guards, or housing. If ANY damage is suspected, STOP and call your dealer
immediately.
Keep children away: Do not allow children to play with or around the unit, which could result in injury. Be
sure the unit is inaccessible to children when not attended.
Power Cable: Only use power cable or jumper cable provided by Euramco Safety for use with RAMFAN
UB20 12V.
Handle with care: Do not drop or throw the unit. Rough treatment can damage the components or wiring and
create a hazardous condition.
Run on stable surface: Start only if blower is sitting in a stable and upright position. While on level surface
and running at full speed, the blower should not move around. If unit is moving, check rubber feet for damage
and replace if necessary.
Secure during transport: When transporting in a vehicle, secure the unit to prevent sliding and possible
injury to vehicle occupants.
During Operation
Airflow Direction: When using the blower, note the directional airflow indicator on the external housing.
Keep out of water: Never operate the unit in pooled or standing water, as this may create a risk of injury
from electrical shock. Do not store outdoors. If electrical wiring or components become wet, thoroughly dry
them before using the unit.
Safety: Proper ear and eye protection must be worn while blower is running. Keep fingers and hands clear of
blade. Do not move blower while it is running.
Keep air intakes clear: Do not clog or block air intakes, this may occur if operated to close to loose
lightweight objects such as clothing or leaves. This can cause the unit to overheat and result in a fire or
electrical hazard.
Keep away dust and dirt: Do not allow dust, dirt, or other particles to be drawn into the air intakes. Dirt in the
motor can cause it to overheat, resulting in a fire or electrical hazard. If the motor gets dirty, clean it using a
compressed air hose.
Allow repair only by qualified person: Immediately stop the unit upon hearing excessive mechanical noise
or vibration. Do not attempt to disassemble or repair the unit if you are not qualified to do so. You can perform
regular maintenance or troubleshooting, however complex problems need to be repaired by an authorized
service technician.

4 | Operation
1. Read the Owner's Manual completely before starting fan.
2. Wear both eye and ear protection.
3. Position the fan on a level surface.
4. Make sure the switch is in the "OFF" position before connecting a power source.
5. This blower is supplied with a 15ft jumper cable that plugs into the blower and is designed to clip to a 12V
vehicle battery. The UB20 12V may be powered by any 12V source with sufficient capacity (See specs in
table above). Battery life will depend on the capacity of the power source.
6. Check vehicle battery, clean terminals.
7. Connect jumper cable to the fan and clamp the ends to the appropriate terminals on a 12V vehicle battery.
When the unit is properly connected to the power source, flip the toggle switch to the “ON”position.
8. Check for proper operation before leaving the unit unattended. Do not move or carry the blower while it is
running.
5 | Maintenance
LOCK-OUT / TAG-OUT: When performing any maintenance, always follow all additional safety precautions
that your company may have for lock-out / tag-out procedures.
POWER OFF: Always turn the power OFF and unplug the unit before performing maintenance procedures. All
the service procedures below are to be executed with the unit unplugged. Perform before each use or as
needed.
DO NOT DISSASSEMBLE blower for maintenance reasons.
INSPECT ELECTRICAL SYSTEM: Inspect the electrical cord for damage at regular intervals. Periodically,
inspect internal wiring for bare wires, insecure fasteners, and discoloration. Remove and repair any damaged
wiring as needed. Failure to do so may lead to electrical shock or a fire hazard.
CLEAN AIR INTAKES: Clean off any accumulated lint or other materials from the finger guards. A build up will
reduce the airflow and may cause the motor to overheat and become a fire hazard. NEVER operate fan with
damaged or missing finger guards.
CLEAN EXTERIOR: Clean fan periodically to remove accumulated dust or particles using a commercially
available biodegradable cleaning solution. DO NOT use solvents containing chlorinated hydrocarbons (i.e.
MEK, Acetone)
EXTERIOR INSPECTION: Evaluate exterior components and make sure they are properly installed. Inspect
the fan for loose fasteners at least once every 6 months depending on frequency of use. Tighten any loose
fasteners immediately. DO NOT overtighten fasteners.
