21V 6+8 Inch Cordless Mini Chainsaw with Batteries & Charger

No complicated professional maintenance is needed for daily home use. After finishing work each time, simply clear wood debris stuck on the chain and guide bar, then add a small amount of lubricant for storage. If the chain becomes dull after repeated cutting, you can sharpen the chain or directly replace the spare chain following the included instruction without sending the machine to repair shops.

It is specially developed for household and horticultural daily use. It works great for trimming fruit tree branches, cutting garden shrubs, chopping small firewood and bamboo materials for home use. It suits courtyard regular maintenance, orchard pruning and lightweight DIY lumber processing. It focuses on small-scale domestic cutting rather than heavy-duty industrial logging of extra-thick hardwood.

Before long-term storage, clean all sawdust and residue on the chain and guide bar thoroughly, apply a thin layer of lubricating oil on the chain to prevent rust. Take the batteries out from the machine and store them separately in a dry, cool indoor place away from direct sunlight and damp environment. Keep all accessories together in a dry storage box to avoid missing parts and component corrosion.

Once the chain clamps tightly in wood, turn off the machine and engage the safety lock first to avoid accidental startup. Slowly wiggle the saw body sideways to release the chain instead of pulling the machine forcibly, which may stretch or break the chain. After taking out the saw, check for chain deformation and add lubricant before continuing subsequent cutting work.
