[NEED REAL IMAGE: Husqvarna 350iB controls and battery location]

Compatible with all Husqvarna 40V BLi batteries. Higher capacity = longer runtime.

Battery System

Blower Won’t Power On

Check:

1. Battery clicked into place
2. Battery has charge (check LED)
3. Safety switch in correct position

If still no power:

• Remove and reseat battery
• Clean contacts with dry cloth
• Test with different BLi battery
• Check for debris in battery slot

Short Runtime

Expected runtime varies by battery and speed:

• BLi200: 12-15 minutes (boost), 30-40 minutes (normal)
• BLi300: 18-22 minutes (boost), 45-55 minutes (normal)

If runtime is drastically reduced:

1. Boost mode usage - drains fast
2. Battery degradation
3. Cold temperature
4. High speed continuous use

Battery Not Charging

Husqvarna charger check:

1. Outlet power confirmed
2. LED indicators respond
3. Contacts clean on both ends
4. Battery at room temperature

Flashing indicators typically mean:

• Too hot - let cool before charging
• Too cold - bring to room temp
• Cell imbalance - may need replacement

Motor and Performance

Motor Won’t Engage

Trigger pressed, no response:

1. Battery charged and seated
2. Trigger moves freely
3. No visible damage

Click but no spin:

• Overload protection active
• Controller issue
• Fan obstruction

Weak Airflow

Less power than expected:

1. Battery charge low
2. Air intake restricted
3. Tube not fully connected
4. Fan damaged

Check intake screen - debris buildup restricts airflow significantly.

Motor Cuts Out

Intermittent operation:

1. Battery connection issue
2. Thermal protection (overheating)
3. Trigger mechanism worn
4. Internal fault

If thermal shutdown: Wait 15 minutes before restarting. Reduce continuous high-speed operation.

Unusual Noises

Normal: Variable speed motor whine Concerning: Grinding, scraping, rattling

For concerning sounds:

• Stop immediately
• Check for debris in housing
• Inspect fan blade
• May need professional service

Boost Mode

The Leaf Blaster’s boost mode provides maximum output.

Boost Not Working

Press boost, no power increase:

1. Battery must have sufficient charge
2. Trigger must be engaged first
3. Button may need cleaning
4. Controller fault possible

Boost Shuts Off Automatically

Boost cuts out during use:

1. Thermal limit - Normal safety feature
2. Battery voltage drop - Charge too low
3. Extended use - Designed for bursts

Boost Drains Battery Quickly

Expected. Boost mode doubles power consumption. Use strategically on tough debris piles.

Physical Components

Tube Connection Issues

Tube loose or falls off:

1. Check locking mechanism
2. Inspect tube collar
3. Clean connection area
4. Replace worn components

Trigger Problems

Sticking or unresponsive trigger:

1. Clean around trigger
2. Check for debris infiltration
3. Dry lubricant on pivot
4. May need trigger replacement

Cruise Control Issues

If equipped with cruise control:

1. Check engagement button
2. Verify at correct speed first
3. May need to reset
4. Mechanism may be worn

Handle Discomfort

Excessive vibration or heat:

1. Check fan balance
2. Motor bearing condition
3. Verify nothing loose internally
4. Normal for extended high-power use

Maintenance

After Each Use

• Remove battery
• Clear intake screen
• Wipe exterior clean
• Store in dry location

Monthly (During Season)

• Deep clean intake area
• Inspect tube for cracks
• Check all connections
• Test trigger mechanism

Annually

• Complete inspection
• Clean all accessible areas

• Avoid extreme temperatures

Troubleshooting Quick Reference

No Power

• Battery seated? Charged?
• Safety switch position?
• Try different battery

Weak Output

• Check battery charge level
• Inspect intake screen
• Verify tube connection
• Use boost for tough debris

Overheating

• Allow cool-down period
• Reduce continuous boost use
• Check for obstructions
• Ensure adequate ventilation

Short Runtime

• Monitor boost usage
• Check battery health
• Cold weather affects runtime
• Consider higher capacity battery

Frequently Asked Questions

How does the 350iB compare to EGO?

Both are top-tier battery blowers. Husqvarna often has better dealer support. EGO has wider retail availability.

Can I use older Husqvarna batteries?

Only 40V BLi series batteries. Not compatible with older 36V system.

Is it powerful enough to replace a gas backpack blower?

For most residential use, yes. Commercial landscape work may still need gas or consider the 580i backpack.

What’s the boost mode useful for?

Wet leaves, packed debris, stubborn piles. Not for general clearing - saves battery using normal speed for light work.
