Husqvarna 226HD75S ユーザーズマニュアル

English

•  The  air  filter,  if  clogged,  will  reduce  the  engine 

performance. Check and clean the filter element in warm, 
soapy water as required. Dry completely before installing. 
If the element is broken or shrunk, replace with a new 
one.

•  How to attach two air filter elements
  1. Attach thin element previously
  2. Attach thick element so that stamp side is outside

•  When the engine runs short of fuel supply, check the fuel 

cap and the fuel filter for blockage.

•  Starting  failure  and  mis-firing  are  often  caused  by  a 

fouled spark plug. Clean the spark plug and check that 
the plug gap is in the correct range. For a replacement 
plug, use the correct type specified by Husqvarna. 

•   REPLACEMENT  PLUG  IS  NGK  CMR7H  OR  CHAMPION 

RZ7C.

•  Note  that  using  any  spark  plug  other  than  those 

designated may result in the engine failing to operate 
properly  or  in  the  engine  becoming  overheated  and 
damaged.

•  To  install  the  spark  plug,  first  turn  the  plug  until  it  is 

finger tight, then tighten it a quarter turn more with a 
socket wrench.

Maintenance, replacement, or repair of the emission control device and systems may be performed by any non-road engine 
repair establishment or individual.
